140667-01-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 140667-01-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,6 and 7 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 140667-01:
(8*1)+(7*4)+(6*0)+(5*6)+(4*6)+(3*7)+(2*0)+(1*1)=112
112 % 10 = 2
So 140667-01-2 is a valid CAS Registry Number.

Electron-donating Behaviour of Aliphatic Carboxylic Acids in the Photoreaction with 1,2,4,5-Tetracyanobenzene
Tsujimoto, Kazuo,Nakao, Nobuhisa,Ohashi, Mamoru
, p. 366 - 367 (1992)
Irradiation of an acetonitrile solution of 1,2,4,5-tetracyanobenzene with aliphatic carboxylic acids gives 2,4,5-tricyanoalkylbenzenes efficiently; electron transfer from the carboxylic acids to the excited tetracyanobenzene is essential.
