Check Digit Verification of cas no

The CAS Registry Mumber 423734-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,3,7,3 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 423734-50:
(8*4)+(7*2)+(6*3)+(5*7)+(4*3)+(3*4)+(2*5)+(1*0)=133
133 % 10 = 3
So 423734-50-3 is a valid CAS Registry Number.

BASICITY AND STRUCTURE OF 5-HYDROXYBENZIMIDAZOLES IN NITROMETHANE

Korolev, B. A.,Osmolovskaya, L. A.,Kuznetsov, Yu. V.,Stolyarova, L. G.,Smirnov, L. D.

, p. 333 - 336 (2007/10/02)

Examination of the acid-base properties of 5-hydroxybenzimidazoles has shown them to exist in nitromethane as the 5-hydroxy-tautomers.Substituents in the 2-position have a predominantly inductive effect on the basicity of the 3-nitrogen, rationalized as in other nitrogen heterocycles by the proximity of the substituents to the reaction center. Keywords: 5-hydroxybenzimidazole, its tautomers and derivatives; acid-base properties and the effect thereon of substituents; Taft and inductive constants.
