Check Digit Verification of cas no

The CAS Registry Mumber 122060-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,6 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122060-59:
(8*1)+(7*2)+(6*2)+(5*0)+(4*6)+(3*0)+(2*5)+(1*9)=77
77 % 10 = 7
So 122060-59-7 is a valid CAS Registry Number.

A Spectrophotometric Study of the Tautomeric Monoanions of (Z)-5-Arylmethylenehydantoins

Tan, Sau-Fun,Ang, Kok-Peng,How, Gee-Fung,Jayachandran, Harilakshmi

, p. 499 - 502 (2007/10/02)

First ionization of (Z)-5-arylmethylenehydantoins in aqueous dimethyl sulphoxide yields a tautomeric mixture of monoanions by deprotonation at N-1 or N-3.By using appropriate 3-methyl and 1-methyl derivatives as models, the equilibrium proportions of the monoanions of the N-substituted compounds have been estimated from the electronic spectra.The percentage of the N-1 anion increases with electron-withdrawing substituents in the benzene ring and with increasing concentration of dimethyl sulphoxide in the solvent mixture.
