Check Digit Verification of cas no

The CAS Registry Mumber 268747-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,8,7,4 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 268747-20:
(8*2)+(7*6)+(6*8)+(5*7)+(4*4)+(3*7)+(2*2)+(1*0)=182
182 % 10 = 2
So 268747-20-2 is a valid CAS Registry Number.

Enantiopure N-protected α-amino glyoxals 1. Synthesis from α-amino acids and some condensation reactions with amines

Darkins, Paul,Groarke, Michelle,McKervey, M. Anthony,Moncrieff, Hazel M.,McCarthy, Noreen,Nieuwenhuyzen, Mark

, p. 381 - 389 (2007/10/03)

A series of N-protected α-ammo diazoketones has been prepared from L-amino acids and dipeptides and used as precursors in the synthesis of novel N-protected α-amino glyoxals via oxidation with distilled dimethyldioxirane (DMD) in acetone. The glyoxals have been converted, without purification, into enantiopure imines, pyrazines, quinoxalines, and pyrido[2,3-b]pyrazines via condensation with the appropriate amine or diamine. The molecular structure of the pyrido[2,3-b]pyrazine derived from N-Cbz-L-phenylalanine has been determined by X-ray analysis.
