Check Digit Verification of cas no

The CAS Registry Mumber 82997-96-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,9,9 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 82997-96:
(7*8)+(6*2)+(5*9)+(4*9)+(3*7)+(2*9)+(1*6)=194
194 % 10 = 4
So 82997-96-4 is a valid CAS Registry Number.

An Efficient Synthesis of 6-Oxopenicillanic and 7-Oxocephalosporanic Acid Derivatives

Hagiwara, Daijiro,Sawada, Kozo,Ohnami, Tetsuo,Aratani, Matsuhiko,Hashimoto, Masashi

, p. 578 - 579 (2007/10/02)

Trifluoromethanesulphonation of benzyl 6-aminopenicillanate (3) and the 7-aminocephalosporanates (7a-c) with (CF3SO2)2O gave the bis(trifluoromethylsulphonate) derivatives (5) and (8a-c), which were then converted into the imines (6) and (9a-c) by treatme
