Check Digit Verification of cas no
The CAS Registry Mumber 31701-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,0 and 1 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31701-42:
(7*3)+(6*1)+(5*7)+(4*0)+(3*1)+(2*4)+(1*2)=75
75 % 10 = 5
So 31701-42-5 is a valid CAS Registry Number.

Preparation of Some 2-(Methoxyphenyl)-2H-benzotriazoles and the Corresponding Hydroxyphenyl Compounds
Rosevear, Judi,Wilshire, John F. K.

The reaction of several substituted o-nitronitrosobenzenes with o- and p-anisidine, and 2,4-dimethoxyaniline in acetic acid gives in good yield the corresponding o-nitroazobenzenes which are readily reduced with thiourea dioxide (formamidinesulfinic acid) to the corresponding 2-(methoxyphenyl)-2H-benzotriazoles, demethylation of which furnished the corresponding 2-(hydroxyphenyl)-2H-benzotriazoles.Demethylation of the dimethoxy derivatives was best accomplished with boron tribromide in methylene chloride, the methoxy group located ortho to the benzotriazole ring beingdemethylated more readily than is the para-methoxy group.The reaction of 0-nitroazobenzenes containing a methoxy group with hydrobromic acid in acetic acid results in cleavage of the azo bond and also partial bromination to give o-nitroaniline and some of its brominated derivatives.
