Check Digit Verification of cas no

The CAS Registry Mumber 640287-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,8 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 640287-64:
(8*6)+(7*4)+(6*0)+(5*2)+(4*8)+(3*7)+(2*6)+(1*4)=155
155 % 10 = 5
So 640287-64-5 is a valid CAS Registry Number.

Design of a New and Highly Effective Chiral Auxiliary for Diels-Alder Reaction of 1-Aminodiene

Robiette, Raphael,Cheboub-Benchaba, Karima,Peeters, Daniel,Marchand-Brynaert, Jaqueline

, p. 9809 - 9812 (2003)

A theoretical investigation of the selectivity of optically active oxazolidin-2-one-substituted dienes has been realized. This analysis enabled the development of (R)-4-phenyloxazolidin-2-thione as a very effective chiral auxiliary for cycloaddition of 1-
