Check Digit Verification of cas no

The CAS Registry Mumber 134240-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,4 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 134240-76:
(8*1)+(7*3)+(6*4)+(5*2)+(4*4)+(3*0)+(2*7)+(1*6)=99
99 % 10 = 9
So 134240-76-9 is a valid CAS Registry Number.

A novel synthesis of esters via substitution of the benzotriazolyl group in 1-(benzotriazol-1-yl)alkyl esters with organozinc reagents

Katritzky,Rachwal,Rachwal

, p. 69 - 73 (1991)

Aldehydes are converted by thionyl chloride and benzotriazole into 1-(1-chloroalyl)benzotriazoles which react with sodium carboxylates to give 1-(benzotriazol-1-yl)alkyl esters. 3. In the alternative route, 3 are prepared by substitution of one of the acetoxy groups in acylals with benzotriazole. The benzotriazolyl moiety in 3 is substituted by an alkyl, an aryl or an alkynyl group upon treatment with an organic reagent in a new versatile synthesis of esters 4.
