Kodi nambala ya CAS imatanthauza chiyani? Kusanthula kwatsatanetsatane kwa "zidziwitso" zamakampani opanga mankhwala
M'makampani opanga mankhwala, nthawi zambiri timakumana ndi mawu akuti CAS nambala, yomwe ndi chizindikiritso chachikulu pamatchulidwe azinthu, nkhokwe zama mankhwala ndi magwiridwe antchito a tsiku ndi tsiku. Kaya mumatchulidwe azinthu, nkhokwe zamankhwala, kapena machitidwe atsiku ndi tsiku amakampani opanga mankhwala, nambala ya CAS ndiyo chizindikiritso chachikulu.Nambala ya CAS imatanthauza chiyani? Nkhaniyi ikupatsani yankho latsatanetsatane.
Kodi nambala ya CAS ndi chiyani?
Nambala ya CAS (Chemical Abstracts Service Number) ndi chizindikiritso chapadera choperekedwa ndi Chemical Abstracts Service (CAS). Mankhwala aliwonse, kaya amachitika mwachilengedwe kapena opangidwa, ali ndi nambala yapadera ya CAS, yomwe imawalola kuti adziwike bwino ndikutsatiridwa padziko lonse lapansi.
Kapangidwe ndi mawonekedwe a nambala ya CAS
Nambala ya CAS nthawi zambiri imakhala ndi magawo atatu a manambala, mwachitsanzo 64-17-5, omwe amayimira zambiri:

Gawo loyamba, lomwe lingasiyane ndi manambala awiri mpaka asanu ndi awiri, limatchula nambala yapadera ya mankhwala;
Gawo lachiwiri nthawi zonse ndi nambala ya manambala awiri, yomwe imagwiritsidwa ntchito poyesa gawo loyamba;
gawo lachitatu ndi chiwerengero cha cheke chimodzi, chomwe chimagwiritsidwa ntchito kutsimikizira kulondola kwa magawo awiri oyambirira a chiwerengerocho.

Kapangidwe kameneka kamalola manambala a CAS kuti apewe kubwereza ndipo amapereka njira yodziwika bwino yodziwira mankhwala.
Kugwiritsa Ntchito ndi Kufunika Kwa Nambala za CAS
Tikamvetsetsa tanthauzo la nambala ya CAS, tiyeneranso kumvetsetsa chomwe chimagwiritsidwa ntchito. cholinga chachikulu cha nambala ya CAS ndikuwonetsetsa kuti mankhwala ndi apadera komanso odziwika padziko lonse lapansi. Popeza kuti mankhwala amatha kukhala ndi mayina angapo ndi ma aliases, kugwiritsa ntchito nambala ya CAS kumapewa chisokonezo. Mwachitsanzo, Ethanol ikhoza kutchedwa mowa, ethyl alcohol, etc. muzochitika zosiyanasiyana, koma nambala yawo ya CAS 64-17-5 ndi yapadera, yomwe imatsimikizira kuti palibe kusamvana poyankhulana pakati pa zinenero zosiyanasiyana ndi madera.
Manambala a CAS amatenga gawo lofunikira pakugula, kutsatsa, kufufuza ndi kasamalidwe kamakampani opanga mankhwala. Mwachitsanzo, mu Safety Data Sheets (SDS), manambala a CAS amagwiritsidwa ntchito kuzindikiritsa momveka bwino mankhwala omwe akukhudzidwa kuti anthu omwe ali ndi chidwi adziŵe bwino lomwe katundu wake ndi zoopsa zomwe zingakhalepo.
Kupeza ndi Kufunsa Nambala za CAS
Ngati mukufuna kuyang'ana nambala ya CAS ya mankhwala, mutha kusaka pamasamba angapo amankhwala apa intaneti, monga CAS Registry, PubChem, ndi ena. Ma databasewa amapereka zambiri zokhudzana ndi mankhwala, kuphatikizapo manambala awo a CAS, mapangidwe a maselo, katundu wa mankhwala, ndi zina.
Kwa makampani, kukhala ndi manambala olondola a CAS sikumangothandiza kasamalidwe ka zinthu, komanso kumathandizira kasamalidwe ka chain chain. Mwachitsanzo, kuwonetsetsa kuti zida zogulidwa ndizofanana ndendende ndi zomwe zimafunikira kuti tipewe zovuta kapena zoopsa zomwe zingachitike.
Mapeto
Yankho la funso la zomwe nambala ya CAS ikutanthauza imapitilira tanthauzo lake lenileni ku gawo lake losasinthika m'makampani opanga mankhwala, pomwe imakhala ngati 'chidziwitso' cha zinthu zamankhwala, kuwonetsetsa kuti zizindikiritso ndi kasamalidwe kolondola padziko lonse lapansi. Kumvetsetsa komanso kugwiritsa ntchito manambala a CAS moyenera ndi luso lofunikira kwa iwo omwe amagwira ntchito m'makampani opanga mankhwala.
