Check Digit Verification of cas no

The CAS Registry Mumber 80680-98-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,8 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 80680-98:
(7*8)+(6*0)+(5*6)+(4*8)+(3*0)+(2*9)+(1*8)=144
144 % 10 = 4
So 80680-98-4 is a valid CAS Registry Number.

THE DEPENDENCE OF ASYMMETRIC INDUCTION ON SOLVENT POLARITY AND TEMPERATURE IN PEPTIDE SYNTHESIS

Benoiton, N. Leo,Kuroda, K.,Chen, F. M. F.

, p. 3361 - 3364 (1981)

When a racemic 2,4-dialkyl-5(4H)-oxazolone reacts with an L-amino acid ester, the D-L epimer is formed in excess in apolar solvents and the L-L epimer is formed in excess in polar solvents, the proportion of L-L isomer increasing with decreasing temperature.
