Check Digit Verification of cas no

The CAS Registry Mumber 4837-21-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,8,3 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4837-21:
(6*4)+(5*8)+(4*3)+(3*7)+(2*2)+(1*1)=102
102 % 10 = 2
So 4837-21-2 is a valid CAS Registry Number.

Copper-Mediated Di- and Monofluoromethanesulfonylation of Arenediazonium Tetrafluoroborates: Probing the Fluorine Effect

Xing, Bo,Ni, Chuanfa,Hu, Jinbo

, p. 206 - 212 (2018/02/06)

A copper-mediated di- and monofluoromethanesulfonylation of arenediazonium tetrafluoroborates using di- and monofluoromethanesulfinate reagents provides aryl difluoromethyl (or monofluoromethyl) sulfones in good yields. It was found that the relative reactivity of these sodium fluoroalkanesulfinates in the present reactions decreases in the following order: CH2FSO2Na > CF2HSO2Na > CF3SO2Na.
