Check Digit Verification of cas no

The CAS Registry Mumber 144457-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,4,5 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 144457-43:
(8*1)+(7*4)+(6*4)+(5*4)+(4*5)+(3*7)+(2*4)+(1*3)=132
132 % 10 = 2
So 144457-43-2 is a valid CAS Registry Number.

Synthesis and characterization of impurity B of S-(+)-clopidogrel bisulfate: An antiplatelet

Reddy, K. Tatendra,Kumar, K. Suneel,Omprakash,Dubey

, p. 1387 - 1396 (2013/05/22)

S-(+)-Clopidogrel bisulfate [(S-(+)-methyl 2-(2-chlorophenyl)-2-(6, 7-dihydrothieno[3, 2-c]pyridin-5(4H)-yl)acetate bisulfate)] is a platelet aggregation inhibitor drug. S-(+)-Clopidogrel bisulfate is prepared by different synthetic approaches in the literature. In almost all the approaches the major impurities known in the literature (A, B, and C) are also listed in the U.S. pharmacopoeia. The control of these pharmaceutical impurities is currently a critical issue to the pharmaceutical industry. In this article, a description of these impurities and their origins in the S-(+)-clopidogrel bisulfate process are presented along with the preparation of impurity B.
