Check Digit Verification of cas no

The CAS Registry Mumber 4724-50-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 4 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4724-50:
(6*4)+(5*7)+(4*2)+(3*4)+(2*5)+(1*0)=89
89 % 10 = 9
So 4724-50-9 is a valid CAS Registry Number.

ACTION OF SULFURIC ACID ON ORGANOPHOSPHORUS COMPOUNDS CONTAINING β-CHLOROSTYRYL GROUPS

Fedorova, G. K.,Anan'eva, L. G.,Yakovchuk, O. A.

, p. 1321 - 1323 (2007/10/02)

By the action of concentrated sulfuric acid on bis(β-chlorostyryl)phosphonic acid and on trichlorobis(β-chlorostyryl)phosphorane with subsequent hydrolysis we obtained, depending on the reactant ratio, diphenacylphosphinic acid or products of its cyclization: 4-hydroxy-2,6-diphenyl-4H-1,4-oxaphosphorin 4-oxide and 4,4'-oxybis.By the action of concentrated sulfuric acid on (β-chlorostyryl)phosphonic acid (or dichloride) and its diesters we obtained phenacylphosphonic acid and its diesters respectively.
