Check Digit Verification of cas no

The CAS Registry Mumber 119191-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,1,9 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 119191-48:
(8*1)+(7*1)+(6*9)+(5*1)+(4*9)+(3*1)+(2*4)+(1*8)=129
129 % 10 = 9
So 119191-48-9 is a valid CAS Registry Number.

Difluorohomologation of ketones

Kosobokov, Mikhail D.,Levin, Vitalij V.,Struchkova, Marina I.,Dilman, Alexander D.

, p. 760 - 763 (2015)

A method for the homologation of ketones with the CF2 fragment is described. The reaction involves silylation, room-temperature difluorocyclopropanation of silyl enol ethers, and selective ring opening of cyclopropanes under acidic conditions. The whole three-step sequence is conveniently performed in a one-pot mode.
