Check Digit Verification of cas no

The CAS Registry Mumber 661464-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,6,1,4,6 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 661464-13:
(8*6)+(7*6)+(6*1)+(5*4)+(4*6)+(3*4)+(2*1)+(1*3)=157
157 % 10 = 7
So 661464-13-7 is a valid CAS Registry Number.

Chromophoric azo reagents for amino acid and peptide labelling

Fraga, Susana M. B.,Goncalves, Maria S. T.,Moura, Joao C. V. P.,Rani, Kavitha

, p. 1750 - 1760 (2007/10/03)

Four carboxylic azo dyes, with spectroscopic absorption peaks ranging from 400 to 500 nm, are presented as new markers for amino acid and peptide labelling at their N-terminus. Labelling can also be performed at side-chain residues as is exemplified with lysine and serine. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004.
