Check Digit Verification of cas no

The CAS Registry Mumber 31485-87-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,8 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 31485-87:
(7*3)+(6*1)+(5*4)+(4*8)+(3*5)+(2*8)+(1*7)=117
117 % 10 = 7
So 31485-87-7 is a valid CAS Registry Number.

Br?nsted acid catalyzed radical addition to quinone methides

Patel, Shiv Shankar,Kumar, Dileep,Tripathi, Chandra Bhushan

, p. 5151 - 5154 (2021)

A fundamental quest for alkyl radical generation under mild conditions through photoinduced Br?nsted acid catalysis is addressed. The optimized protocol does not require any organic dyes or transition metal photocatalyst. Under blue light irradiation with diphenyl phosphate as a catalyst and dihydropyridine derivatives as a radical source, functionalized arylmethane derivatives are obtained in high yield.
