Check Digit Verification of cas no

The CAS Registry Mumber 99346-30-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,3,4 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99346-30:
(7*9)+(6*9)+(5*3)+(4*4)+(3*6)+(2*3)+(1*0)=172
172 % 10 = 2
So 99346-30-2 is a valid CAS Registry Number.

THE TRAPPING OF SULFENIC ACIDS FROM PENICILLIN SULFOXIDES. ARYL MERCAPTANS

Micetich, Ronald G.,Maiti, Samarendra N.,Tanaka, Motoaki,Yamazaki, Tomio,Ogawa, Kazuo

, p. 1403 - 1409 (2007/10/02)

Aryl mercaptans, unlike heterocyclic mercaptans, reacted exceptionally slowly with penicillin sulfoxides.These reactions are affected by the substituent at the C-6 position of the penam, and by the nature of the ester group at the C-3 position.The unsym- azetidinone disulfides obtained from these reactions, unlike those from heterocyclic mercaptans, did not react with halogenating agents such as cupric chloride.
