Check Digit Verification of cas no

The CAS Registry Mumber 124731-69-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,3 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 124731-69:
(8*1)+(7*2)+(6*4)+(5*7)+(4*3)+(3*1)+(2*6)+(1*9)=117
117 % 10 = 7
So 124731-69-7 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.
