67131-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67131-61-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,1,3 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67131-61:
(7*6)+(6*7)+(5*1)+(4*3)+(3*1)+(2*6)+(1*1)=117
117 % 10 = 7
So 67131-61-7 is a valid CAS Registry Number.

Carbanion Photochemistry. 2. Kinetic Control of Product Formation in Reactions of Radicals with Carbanions
Tolbert, Laren M.
, p. 3531 - 3534 (1980)
The interaction of resonance-stabilized carbanions with methyl radicals produced by the irradiation of the carbanions in dimethyl sulfoxide is governed by the pKa of the carboanion conjugate acid to a greater extent than by the stability of the
