Check Digit Verification of cas no

The CAS Registry Mumber 6548-10-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,4 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6548-10:
(6*6)+(5*5)+(4*4)+(3*8)+(2*1)+(1*0)=103
103 % 10 = 3
So 6548-10-3 is a valid CAS Registry Number.

Photochemical generation of difluoromethyl radicals having various functional groups and their highly regioselective addition to olefins and aromatic substitution

Nagura, Hirokatsu,Murakami, Satoru,Fuchigami, Toshio

, p. 10237 - 10245 (2007)

Difluoromethyl radicals bearing ester, phosphonate, nitrile, cyclic carbonate, and carbamate groups were generated by the photoinitiated S-CF2 bond cleavage of electrosynthesized α,α-difluorosulfides, and their addition to olefins and aromatic substitution were successfully carried out to provide the regioselective adducts and substitution products in moderate yields. The yields of substitution products increased by the addition of diphenyl diselenide and 2,4,6-trimethylpyridine.
