Check Digit Verification of cas no

The CAS Registry Mumber 91173-62-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,1,7 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 91173-62:
(7*9)+(6*1)+(5*1)+(4*7)+(3*3)+(2*6)+(1*2)=125
125 % 10 = 5
So 91173-62-5 is a valid CAS Registry Number.

CHEMISTRY OF OXALYL DERIVATIVES OF METHYL KETONES. XXXVI. REACTION OF DIPHENYLDIAZOMETHANE WITH ARYLSULFONYLPYRUVIC ESTERS

Andreichikov, Yu.S.,Gein, V.L.,Shapet'ko, N.N.

, p. 757 - 762 (2007/10/02)

Diphenyldiazomethane reacts with arylsulfonylpyruvic esters, forming O-alkylation products, oxetanes, and 1,3-dioxolanes.The thermal rearrangement of the O-alkylation products into ethyl 2-oxo-3-(arylsulfonyl)-4,4-diphenylbutyrates was discovered.
