Check Digit Verification of cas no

The CAS Registry Mumber 139225-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,2 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139225-95:
(8*1)+(7*3)+(6*9)+(5*2)+(4*2)+(3*5)+(2*9)+(1*5)=139
139 % 10 = 9
So 139225-95-9 is a valid CAS Registry Number.

Novel Synthesis of Conjugated Bisperfluoroalkyl Enynes

Shen, Yanchang,Xiang, Yuejun,Qiu, Weiming

, p. 2965 - 2968 (2007/10/02)

Conjugated bisperfluoroalkyl enynes can be conveniently synthesized in 85-99percent yield by vacuum pyrolysis of (perfluoroacyl)methylene>triphenylphosphoranes which were generated from the corresponding methylene triphenylphosphoranes via double perfluoroacylation in a one-pot reaction.
