Check Digit Verification of cas no

The CAS Registry Mumber 65781-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,7,8 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65781-18:
(7*6)+(6*5)+(5*7)+(4*8)+(3*1)+(2*1)+(1*8)=152
152 % 10 = 2
So 65781-18-2 is a valid CAS Registry Number.

Electrophilic, catalytic alkylation of polyfluoroolefins by some fluoroalkanes

Belen'Kii,Petrov,Resnick

, p. 15 - 20 (2001)

New data are presented on the antimony pentafluoride catalyzed reaction of hydrofluorocarbons such as CH3F, CH2F2, CH3CHF2 and RfCH2CH2F with fluoroolefins. The condensation of CH2F2 and fluoroolefins CF2=CFX (X=F, CF3) proceeds under mild conditions producing the corresponding propanes FCH2CFXCF3 in moderate to high yield. Under similar conditions methyl fluoride reacts with tetrafluoroethylene giving CH3CF2CF3. However, a complex mixture of products forms in the analogous reaction with hexafluoropropene. The structures of the products of the reactions of CH3CHF2 and tetrafluoroethylene and F-butylethylene were determined.
