82278-19-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82278-19-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,7 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 82278-19:
(7*8)+(6*2)+(5*2)+(4*7)+(3*8)+(2*1)+(1*9)=141
141 % 10 = 1
So 82278-19-1 is a valid CAS Registry Number.

Palladium(II)-catalyzed directed trifluoromethylthiolation of unactivated C(sp3)-H bonds

Xiong, Heng-Ying,Besset, Tatiana,Cahard, Dominique,Pannecoucke, Xavier

, p. 4204 - 4212 (2015)

The synthesis of trifluoromethylthiolated aliphatic acid derivatives by Pd-catalyzed C(sp3)-H bond functionalization was developed. Using a bidentate directing group, the direct and selective introduction of a SCF3 moiety was possible on a range of amides with remarkable selectivity for C(sp3)-centers with an electrophilic SCF3 source and pivalic acid as an additive. This work constitutes an example of the unactivated C(sp3)-SCF3 bond formation by C-H activation offering a new access to relevant molecules.
