Check Digit Verification of cas no

The CAS Registry Mumber 91177-12-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91177-12:
(7*9)+(6*1)+(5*1)+(4*7)+(3*7)+(2*1)+(1*2)=127
127 % 10 = 7
So 91177-12-7 is a valid CAS Registry Number.

Reductive rearrangements of silylated penicillin G 1-oxide

Van Der Klein, Pieter A. M.,Witkamp, Henk A.,De Vroom, Erik

, p. 8691 - 8692 (2007/10/02)

The reaction of penicillin G I-oxide with BSU followed by treatment with tributyl phosphite gives, after hydrolysis, crystalline thiazoline azetidinone 2. Addition of triethylamine after reduction resulted in the formation of the isomeric thiazoline azetidinone 3.
