Check Digit Verification of cas no

The CAS Registry Mumber 1188447-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,8,4,4 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1188447-75:
(9*1)+(8*1)+(7*8)+(6*8)+(5*4)+(4*4)+(3*7)+(2*7)+(1*5)=197
197 % 10 = 7
So 1188447-75-7 is a valid CAS Registry Number.

Novel highly proton conductive sulfonated poly(p-phenylene) from 2,5-dichloro-4-(phenoxypropyl)benzophenone as proton exchange membranes for fuel cell applications

Seesukphronrarak, Surasak,Ohira, Akihiro

, p. 4744 - 4746 (2009)

A novel sulfonated poly(4-phenoxypropylbenzoyl-1,4-phenylene) introducing a flexible alkyl chain was synthesized and achieved high proton conductivity even at low humidity (SPP: 0.077 S cm-1, Nafion 112: 0.029 S cm -1 at 80 °C 50% RH
