Check Digit Verification of cas no

The CAS Registry Mumber 211935-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,9,3 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 211935-52:
(8*2)+(7*1)+(6*1)+(5*9)+(4*3)+(3*5)+(2*5)+(1*2)=113
113 % 10 = 3
So 211935-52-3 is a valid CAS Registry Number.

Difluoromethylation of Alkyl Bromides and Iodides with TMSCF2H

Zhao, Haiwei,Lu, Changhui,Herbert, Simon,Zhang, Wei,Shen, Qilong

supporting information, p. 2854 - 2865 (2021/02/06)

We describe, for the first time, two protocols for direct difluoromethylation of unactivated alkyl bromides and iodides. Reactions of alkyl iodides with TMSCF2H were mediated by a copper catalyst using CsF as the activator, while reactions of less reactive alkyl bromides required a combination of palladium and a stoichiometric amount of CuI as the catalysts. Preliminary mechanistic studies of the synergistic Pd/Cu-catalyzed difluoromethylation of alkyl bromides suggest that it proceeds likely via a Pd(I)/Pd(III) catalytic cycle.
