Check Digit Verification of cas no
The CAS Registry Mumber 339-48-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 339-48:
(5*3)+(4*3)+(3*9)+(2*4)+(1*8)=70
70 % 10 = 0
So 339-48-0 is a valid CAS Registry Number.

Nonconventional difluoroalkylation of C(sp2)-H bonds through hydroarylation

An unprecedented Rh-catalyzed C2-difluoroalkylation of indole derivatives with 2,2-difluorovinyl arenesulfonates has been reported. This reaction provides a rare instance of catalytic difluoroalkylation through hydroarylation of gem-difluoroalkenes. The sulfonate group works as a chelating ligand, thus stabilizing the rhodacycle intermediate, leading to the uncommon transformation.
