Check Digit Verification of cas no
The CAS Registry Mumber 123133-12-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,1,3 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123133-12:
(8*1)+(7*2)+(6*3)+(5*1)+(4*3)+(3*3)+(2*1)+(1*2)=70
70 % 10 = 0
So 123133-12-0 is a valid CAS Registry Number.

A Novel Generation and Behavior of Alkylfluorocarbenoids from α,α-Chlorofluoroalkyl Sulfoxides
Uno, Hidemitsu,Semba, Fumihiko,Tasaka, Tadataka,Suzuki, Hitomi
, p. 309 - 312 (1989)
α,α-Chlorofluoroalkyl sulfoxides undergo nucleophilic desulfinylation with a Grignard reagent to give alkylfluorocarbenoids which collapse into cis-fluoroalkenes in the presence of copper(I) iodide.
