1608124-41-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1608124-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,8,1,2 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1608124-41:
(9*1)+(8*6)+(7*0)+(6*8)+(5*1)+(4*2)+(3*4)+(2*4)+(1*1)=139
139 % 10 = 9
So 1608124-41-9 is a valid CAS Registry Number.

Highly efficient Cu(I)-catalyzed trifluoromethylation of aryl(heteroaryl) enol acetates with CF3 radicals derived from CF3SO 2Na and TBHP at room temperature

Lu, Yang,Li, Yaming,Zhang, Rong,Jin, Kun,Duan, Chunying

, p. 128 - 133 (2014/05/06)

An efficient method for the Cu(I)-catalyzed synthesis of α-trifluoromethyl ketones via the addition of CF3 to aryl(heteroaryl) enol acetates by using the readily available CF 3SO2Na (Langlois reagent) has been developed. The reaction is experimentally simple and carried out at room temperature, providing good to excellent yields with wide functional group tolerance.
