74835-71-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74835-71-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,3 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74835-71:
(7*7)+(6*4)+(5*8)+(4*3)+(3*5)+(2*7)+(1*1)=155
155 % 10 = 5
So 74835-71-5 is a valid CAS Registry Number.

Reactions of Perfluorocycloalkenones with Nucleophiles
Card, Peter J.,Smart, Bruce E.
, p. 4429 - 4432 (2007/10/02)
The reactions of perfluorocyclopent-2-en-1-one and perfluorocyclobutenone with various nucleophiles have been studied. The enones are attacked by nucleophiles at C-3 via an addition-elimination sequence to afford the 3-substituted perfluorinated enones. M
