Check Digit Verification of cas no

The CAS Registry Mumber 101382-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,3,8 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 101382-81:
(8*1)+(7*0)+(6*1)+(5*3)+(4*8)+(3*2)+(2*8)+(1*1)=84
84 % 10 = 4
So 101382-81-4 is a valid CAS Registry Number.

A Tactically Novel Alternative to Acyclic Stereoselection Based on the Concept of a Replicating Chiron - 1,5-C-Methyl Substitution

Hanessian, Stephen,Murray, Peter J.,Sahoo, Soumya P.

, p. 5623 - 5626 (2007/10/02)

A synthetic sequence is described wherein a chiral butyrolactone is used as a template to control the stereochemistry of a C-methylation process on the corresponding enolate.A sequential two-carbon homologation and replication of the butyrolactone template allows a second stereocontrolled C-methylation.The ultimate outcome is a seven carbon acyclic chain with a predicable 1,5-substitution pattern of C-methyl groups with or without an intervening hydroxyl group.
