Check Digit Verification of cas no

The CAS Registry Mumber 82379-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,3,7 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82379-22:
(7*8)+(6*2)+(5*3)+(4*7)+(3*9)+(2*2)+(1*2)=144
144 % 10 = 4
So 82379-22-4 is a valid CAS Registry Number.

SYNTHESIS AND ABSOLUTE CONFIGURATION OF THREE ISOMERIC SPIRO-BIS(2-PYRROLIDINONES)

Kajtar, Marton,Hollosi, Miklos,Kinsky, Klaus,Majer, Zsuzsanna

, p. 936 - 949 (2007/10/02)

Syntheses are described for three isomeric spiro-bis-(2-pyrrolidinones): 2,7-diazaspirononane-3,8-dione (II), 2,7-diazaspirononane-1,8-dione (IV) and 1,7-diazaspirononane-2,8-dione (VI).All the syntheses were carried out starting from 3-carboxy-5-oxo-3-pyrrolidineacetic acid (VIII) of known configuration, allowing the assignation of absolute configuration to compounds II, IV and VI synthetized through stereochemically unequivocal reaction steps.
