Kodi nambala ya CAS ndi chiyani?

TheNambala ya CASndi chizindikiritso chodziwika padziko lonse lapansi cha zinthu zamakhemikolo. M'nthawi yamasiku ano yazamalonda komanso kudalirana kwapadziko lonse lapansi, manambala a CAS amatenga gawo lofunikira pakuzindikiritsa mankhwala. Chifukwa chake, ofufuza ochulukirachulukira, opanga, amalonda, ndi ogwiritsa ntchito mankhwala amafunikira magwiritsidwe a nambala ya CAS, ndipo akuyembekeza kumvetsetsa zambiri za nambala ya CAS ndi kugwiritsa ntchito manambala a CAS.
1.Kodi nambala ya CAS ndi chiyani?
Nawonso database ya CAS (Chemical Abstract Service) imasamalidwa ndi Chemical Abstracts Society (CAS), yomwe ndi nthambi ya American Chemical Society. Imasonkhanitsa zinthu zama mankhwala kuchokera m'mabuku asayansi kuyambira 1957 ndipo ndiye nkhokwe yovomerezeka kwambiri yazambiri zamankhwala. Mankhwala omwe ali mgululi atha kuyambika kumayambiriro kwa zaka za m'ma 1900, ndipo masauzande azinthu zatsopano amasinthidwa tsiku lililonse.
Chigawo chilichonse chamankhwala chomwe chatchulidwa chimapatsidwa Nambala ya Registry ya CAS (CAS RN), yomwe ndi nambala yozindikiritsa yamankhwala. Pafupifupi nkhokwe zonse zamankhwala zimalola kubweza zinthu pogwiritsa ntchito manambala a CAS.
Nambala ya CAS ndi chizindikiritso cha manambala chomwe chimakhala ndi manambala mpaka 10 ndipo chimagawidwa m'magawo atatu ndi hyphen. Nambala yakumanja kwambiri ndi cheke chomwe chimagwiritsidwa ntchito kutsimikizira kuti nambala yonse ya CAS ndi yolondola komanso yapadera.
2.Chifukwa chiyani ndikufunika kugwiritsa ntchito / kufufuza nambala ya CAS?
Mankhwala amatha kufotokozedwa m'njira zosiyanasiyana, monga ma formula a mamolekyu, mawonekedwe a kamangidwe, mayina adongosolo, mayina odziwika, kapena mayina amalonda. Komabe, nambala ya CAS ndi yapadera ndipo imagwira ntchito ku chinthu chimodzi chokha. Chifukwa chake, nambala ya CAS ndi mulingo wapadziko lonse lapansi womwe umagwiritsidwa ntchito kudziwa zinthu zamankhwala, zomwe zimadaliridwa ndi asayansi, mafakitale, ndi mabungwe owongolera omwe akufunika chidziwitso chovomerezeka.
Kuonjezera apo, mu malonda enieni a mabizinesi, nthawi zambiri zimakhala zofunikira kupereka chiwerengero cha CAS cha mankhwala, monga kusungitsa mankhwala amtundu, kusinthana kwa mankhwala akunja, kulembetsa mankhwala (monga TSCA declaration ku United States), ndi ntchito ya INN ndi USAN.
Nambala za CAS za zinthu zodziwika bwino zitha kupezeka m'malo opezeka pagulu, koma pazinthu zomwe zili ndi chitetezo cha patent kapena zinthu zomwe zangopangidwa kumene, manambala awo a CAS atha kupezeka pofufuza kapena kugwiritsa ntchito ku American Chemical Abstracts Service.
3. Ndi zinthu ziti zomwe zingagwiritsidwe ntchito pa nambala ya CAS?
CAS Society imagawaniza zinthu zomwe zitha kugwiritsa ntchito manambala a CAS m'magulu 6 otsatirawa:

Kuphatikiza apo, kusakaniza sikungagwire ntchito pa nambala ya CAS, koma gawo lililonse la osakaniza litha kugwiritsa ntchito nambala ya CAS padera.
Zinthu zomwe sizikuphatikizidwa pamapulogalamu anthawi zonse a CAS ndi: gulu lazinthu, zinthu, zamoyo, zamoyo, chomera, ndi dzina lamalonda, monga ma amine onunkhira, shampu, chinanazi, botolo lagalasi, pawiri yasiliva, ndi zina zambiri.

4.Ndi chidziwitso chotani chomwe chimafunikira pakufunsira / kufunsa nambala ya CAS?
Pamitundu ya 6 yomwe ili pamwambapa, CAS Society yapereka zofunikira zazidziwitso, ndipo imalimbikitsanso kuti ofunsira apereke chidziwitso chatsatanetsatane chazinthu ndi chidziwitso chofunikira chothandizira momwe angathere, zomwe zimathandiza CAS Society kuzindikira molondola komanso moyenera zinthu zomwe zimagwiritsidwa ntchito, kupewa kuwongolera, ndi kusunga ndalama zofunsira.

5. Nambala ya CAS yofunsira / njira yofunsira
① Njira yokhazikika yofunsira/kufunsa manambala a CAS ndi:
② Wopemphayo amakonzekera zinthu zomwe zikufunikira ndikutumiza fomuyo
③ Ndemanga yovomerezeka
④ Zowonjezera zambiri (ngati zilipo)
⑤ Ndemanga zovomerezeka pazotsatira zamapulogalamu
⑥ Kutulutsa kovomerezeka kwa invoice yolipirira (nthawi zambiri pakatha milungu iwiri zotsatira zofunsira zitaperekedwa)
⑦ Wolemba ntchito amalipira ndalama zoyendetsera ntchito
Kagwiritsidwe ntchito/kafukufuku: Nthawi yoyankha movomerezeka ndi masiku 10 ogwira ntchito, ndipo nthawi yokonza maoda mwachangu ndi masiku atatu ogwira ntchito. Nthawi yokonza siyikuphatikizidwa mumayendedwe opangira.
6. Mafunso wamba okhudza manambala a CAS
① Kodi zomwe zili mu nambala ya CAS ntchito/zotsatira zamafunso?
Nthawi zambiri imaphatikizapo Nambala Yolembera ya CAS (mwachitsanzo nambala ya CAS) ndi Dzina la Index la CA (ie dzina la CAS).
Ngati pali kale nambala yofananira ya CAS ya zinthu zomwe zagwiritsidwa ntchito, wogwira ntchitoyo azidziwitsa nambala ya CAS; Ngati chinthu chogwiritsidwa ntchito chilibe nambala yofananira ya CAS, nambala yatsopano ya CAS idzaperekedwa. Pakadali pano, zinthu zomwe zikugwiritsidwa ntchito zidzaphatikizidwa poyera mu nkhokwe ya CAS REGISTRY. Ngati mukufuna kusunga zinsinsi, mutha kulembetsa dzina la CAS lokha.
② Kodi zambiri zanu zimawululidwa panthawi yofunsira / kufunsa nambala ya CAS?
Ayi, ayi. Njira yofunsira nambala ya CAS ndi yachinsinsi kwambiri, ndipo kampani ya CAS ili ndi ndondomeko yosunga zinsinsi zonse komanso mwadongosolo. Popanda chilolezo cholembedwa, CAS ingokambirana mwatsatanetsatane ndi munthu amene watumiza fomuyo.
③ Chifukwa chiyani dzina lovomerezeka la CA Index silikufanana ndendende ndi dzina loperekedwa ndi wofunsira mwiniwake?
Dzina la CAS ndi dzina lovomerezeka loperekedwa ku chinthu chotengera dzina la CA Index Name, ndipo nambala iliyonse ya CAS imagwirizana ndi dzina lapadera la CAS. Mayina omwe amaperekedwa ndi wopemphayo nthawi zina amatha kutchulidwa molingana ndi malamulo ena a mayina monga IUPAC, ndipo ena angakhale osagwirizana kapena olakwika.
Chifukwa chake, dzina loperekedwa ndi wopemphayo limangogwiritsidwa ntchito pofunsira / kufunsa CAS, ndipo dzina lomaliza la CAS liyenera kutengera dzina loperekedwa ndi CAS Society. Zachidziwikire, ngati wopemphayo ali ndi mafunso okhudzana ndi zotsatira zofunsira, atha kulumikizananso ndi CAS.
BTF Testing Lab ndi malo oyesera ovomerezeka ndi China National Accreditation Service for Conformity Assessment (CNAS), nambala: L17568. Pambuyo pakukula kwazaka zambiri, BTF ili ndi labotale yofananira ndi ma electromagnetic, labotale yolumikizirana opanda zingwe, labotale ya SAR, labotale yachitetezo, labotale yodalirika, labotale yoyezetsa ma batire, kuyezetsa mankhwala ndi ma labotale ena. Imayenderana bwino ndi ma elekitirodi, ma frequency a wailesi, chitetezo chazinthu, kudalirika kwa chilengedwe, kusanthula kulephera kwa zinthu, ROHS/REACH ndi kuyesa kwina. BTF Testing Lab ili ndi malo oyezera akatswiri komanso athunthu, gulu lazoyeserera ndi akatswiri a certification, komanso kuthekera kothana ndi zovuta zosiyanasiyana zoyesa ndi ziphaso. Timatsatira mfundo zotsogola za "chilungamo, kusakondera, kulondola, ndi kukhwima" ndikutsata mosamalitsa zofunikira za ISO/IEC 17025 test and calibration laboratory management system for science management. Tadzipereka kupatsa makasitomala ntchito zabwino kwambiri. Ngati muli ndi mafunso, chonde omasuka kulankhula nafe nthawi iliyonse.
