Check Digit Verification of cas no

The CAS Registry Mumber 99457-86-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,4,5 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 99457-86:
(7*9)+(6*9)+(5*4)+(4*5)+(3*7)+(2*8)+(1*6)=200
200 % 10 = 0
So 99457-86-0 is a valid CAS Registry Number.

Auxiliary Structure and Asymmetric Induction in the Ene Reactions of Chiral Glyoxylates

Whitesell, James K.,Lawrence, Robert M.,Chen, Huang-Hsing

, p. 4779 - 4784 (2007/10/02)

A variety of chiral auxiliares (1a-13a) were prepared and tested for levels of asymmetric induction control in the ene reaction of chiral glyoxylates.Structural features required for high levels of control were defined by systematic modification of the auxiliary, providing systems with induction levels that ranged from 1.2 to 1 to better than 99.9 to 0.1.
