Check Digit Verification of cas no

The CAS Registry Mumber 114221-71-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,2,2 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 114221-71:
(8*1)+(7*1)+(6*4)+(5*2)+(4*2)+(3*1)+(2*7)+(1*1)=75
75 % 10 = 5
So 114221-71-5 is a valid CAS Registry Number.

Free-Radical Additions of Diselenides to Dimethyl Acetylenedicarboxylate, Methyl Propiolate, and Dimethyl Maleate

Back, Thomas G.,Krishna, M. Vijaya

, p. 2533 - 2536 (2007/10/02)

The photolysis of diphenyl or dimesityl diselenide with dimethyl acetylenedicarboxylate or methyl propiolate resulted principally in the formation of the corresponding vicinal bisselenides 1a,b,2a,b, and 6a,b via a free-radical chain addition mechanism.Dimethyl maleate underwent a selenyl radical mediated isomerization to dimethyl fumarate when similarly photolyzed with diphenyl diselenide.
