75682-81-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75682-81-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,6,8 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 75682-81:
(7*7)+(6*5)+(5*6)+(4*8)+(3*2)+(2*8)+(1*1)=164
164 % 10 = 4
So 75682-81-4 is a valid CAS Registry Number.

Synthesis of 2-Trifluoromethylcyclohexenones from 2,2,2-Trifluoroethyl Vinyl Ketone
Molines, Huguette,Wakselman, Claude
, p. 1114 - 1117 (2007/10/02)
2,2,2-Trifluoroethyl vinyl ketone is prepared in two steps from β-chloropropionyl fluoride and 1,1-difluoroethylene.Condensation of this reagent with enamines or ketols leads to the formation of 2-trifluoromethylcyclohexenones.
