649727-93-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 649727-93-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,2 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 649727-93:
(8*6)+(7*4)+(6*9)+(5*7)+(4*2)+(3*7)+(2*9)+(1*3)=215
215 % 10 = 5
So 649727-93-5 is a valid CAS Registry Number.

Electrochemical fluorosulfation of perfluoroallylbenzene
Sterlin, Sergei R.,Grinberg, Vitali A.
, p. 183 - 187 (2007/10/03)
Perfluoroallylbenzene (I) can be isomerized under the action of HSO3F to form perfluoropropenylbenzene (in the form of a mixture of cis- and trans-isomers) which undergoes anodic oxidation in HSO3F to give α,β-bis(fluorosulfonyloxy)
