Check Digit Verification of cas no

The CAS Registry Mumber 88557-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,5,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 88557-20:
(7*8)+(6*8)+(5*5)+(4*5)+(3*7)+(2*2)+(1*0)=174
174 % 10 = 4
So 88557-20-4 is a valid CAS Registry Number.

REVISION OF THE ABSOLUTE CONFIGURATION OF A-FACTOR; THE INDUCER OF STREPTOMYCIN BIOSYNTHESIS, BASING ON THE RECONFIRMED (R)-CONFIGURATION OF (+)-PARACONIC ACID

Mori, Kenji

, p. 3107 - 3109 (2007/10/02)

(+)-Paraconic acid was shown to be of (R)-configuration by its four-step conversion to (R)-(+)-3-methyl-4-butanolide.The absolute configuration at C-3 of A-factor was therefore revised to be R, since it was synthesized from (S)-(-)-paraconic acid.
