Check Digit Verification of cas no

The CAS Registry Mumber 389142-57-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,9,1,4 and 2 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 389142-57:
(8*3)+(7*8)+(6*9)+(5*1)+(4*4)+(3*2)+(2*5)+(1*7)=178
178 % 10 = 8
So 389142-57-8 is a valid CAS Registry Number.

Synthesis of perfluorinated carboxylic acid membrane monomers by utilizing liquid-phase direct fluorination

Okazoe, Takashi,Watanabe, Kunio,Itoh, Masahiro,Shirakawa, Daisuke,Kawahara, Kengo,Tatematsu, Shin

, p. 521 - 527 (2005)

A new synthetic procedure for the preparation of perfluorinated carboxylic acid membrane monomers from non-fluorinated compounds has been developed. A key step in the synthetic route is liquid-phase direct fluorination reaction with elemental fluorine. Direct fluorination of a partially fluorinated diester, which was prepared from a hydrocarbon diol and a perfluorinated acyl fluoride, followed by thermal elimination, gave a perfluorinated diacyl fluoride, which is a precursor of a perfluorinated carboxylic acid membrane monomer.
