1431374-77-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1431374-77-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,1,3,7 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1431374-77:
(9*1)+(8*4)+(7*3)+(6*1)+(5*3)+(4*7)+(3*4)+(2*7)+(1*7)=144
144 % 10 = 4
So 1431374-77-4 is a valid CAS Registry Number.

Noncatalytic pyridyl-directed alkylation and arylation carbon-fluorine bond of polyfluoroarenes with grignard reagents
Xiong, Yang,Wu, Jingjing,Xiao, Senhan,Xiao, Juan,Cao, Song
, p. 4599 - 4603 (2013)
Cross-coupling reaction of polyfluoroarenes with Grignard reagents via pyridine-directed cleavage of C-F bond in the absence of metal catalysts was developed. A possible mechanism was suggested.
