Check Digit Verification of cas no
The CAS Registry Mumber 188690-78-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,6,9 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188690-78:
(8*1)+(7*8)+(6*8)+(5*6)+(4*9)+(3*0)+(2*7)+(1*8)=200
200 % 10 = 0
So 188690-78-0 is a valid CAS Registry Number.

A study of the thermal decarboxylation of three perfluoropolyether salts
Marchionni, Guiseppe,Petricci,Spataro,Pezzin
, p. 123 - 130 (2007/10/03)
The thermal decarboxylation of three dicarboxylic perfluoropolyether potassium salts of relatively short chain length has been investigated and the products and kinetics of the main reactions have been defined. From the rate constants and Arrhenius parameters data, the second decarboxylation appears to be quantitatively rather close to the first.
