1422444-40-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1422444-40-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,2,4,4 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1422444-40:
(9*1)+(8*4)+(7*2)+(6*2)+(5*4)+(4*4)+(3*4)+(2*4)+(1*0)=123
123 % 10 = 3
So 1422444-40-3 is a valid CAS Registry Number.

PhI(OAc)2-mediated oxidative trifluoromethylation of arenes with CF3SiMe3 under metal-free conditions
Wu, Xinyue,Chu, Lingling,Qing, Feng-Ling
, p. 249 - 251 (2013)
A PhI(OAc)2-mediated oxidative trifluoromethylation of arenes with CF3SiMe3 under metal-free conditions has been described. This protocol precludes the need of substrate pre-functionalization and metal catalysts, enabling
