Check Digit Verification of cas no

The CAS Registry Mumber 135215-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,2,1 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 135215-54:
(8*1)+(7*3)+(6*5)+(5*2)+(4*1)+(3*5)+(2*5)+(1*4)=102
102 % 10 = 2
So 135215-54-2 is a valid CAS Registry Number.

Investigation of a Model for 1,2-Asymmetric Induction in Reactions of α-Carbalkoxy Radicals: A Stereochemical Comparison of Reactions of α-Carbalkoxy Radicals and Ester Enolates

Hart, David J.,Krishnamurthy, Ramanarayanan

, p. 4457 - 4470 (1992)

The stereochemical course of reductions and allylations of α-carbalkoxy radicals with chiral centers at the β-position are reported.Radicals without polar substituents, with alkoxyl or acetoxyl groups, and with hydroxyl groups at the β-position were exami
