Check Digit Verification of cas no

The CAS Registry Mumber 118459-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,4,5 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 118459-72:
(8*1)+(7*1)+(6*8)+(5*4)+(4*5)+(3*9)+(2*7)+(1*2)=146
146 % 10 = 6
So 118459-72-6 is a valid CAS Registry Number.

Model studies directed toward the total synthesis of 14-membered cyclopeptide alkaloids: Synthesis of prolyl peptides via a four-component condensation

Bowers, Margaret M.,Carroll, Patrick,Joullie, Madeleine M.

, p. 857 - 865 (2007/10/02)

The general applicability of a four-component condensation for the formation of N-acyl-β-aryloxyprolines has been demonstrated in several model studies. The relative stereochemistry of the diastereoisomers obtained has been assigned from 1H n.m.r. studies, and confirmed by an X-ray analysis of one of the stereoisomers.
