87996-63-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87996-63-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,9 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87996-63:
(7*8)+(6*7)+(5*9)+(4*9)+(3*6)+(2*6)+(1*3)=212
212 % 10 = 2
So 87996-63-2 is a valid CAS Registry Number.

SULFOXIDES OF PENICILLINATES WITH NON CLASSICAL SUBSTITUENTS IN THE 6-POSITION
Adam, S.,Arnold, W.,Schoenholzer, P.
, p. 2485 - 2491 (2007/10/02)
(6Z and 6E)-6-acetonylidenepenicillanates and (6R)-6-acetonylpenicillanates were prepared and the directing influence of keto-group on the stereochemical course of the oxidation at the S with m-chloroperbenzoic acid was determined.
