Check Digit Verification of cas no

The CAS Registry Mumber 1217896-67-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,8,9 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1217896-67:
(9*1)+(8*2)+(7*1)+(6*7)+(5*8)+(4*9)+(3*6)+(2*6)+(1*7)=187
187 % 10 = 7
So 1217896-67-7 is a valid CAS Registry Number.

Triphenylamine-based dyes bearing functionalized 3,4- propylenedioxythiophene linkers with enhanced performance for dye-sensitized solar cells

Liang, Yanliang,Peng, Bo,Liang, Jing,Tao, Zhanliang,Chen, Jun

supporting information; experimental part, p. 1204 - 1207 (2010/06/13)

Chemical Equation Presented Introduction of modified 3,4-propylenedioxythiophene units into triphenylamine-based dyes is found to enhance light capturing, suppress dye aggregation, and remarkably retard charge recombination in dye-sensitized solar cells. Open circuit voltages of the as-synthesized dyes (～800 mV) are much higher than that with a thiophene congener (720 mV) under similar conditions as a result of self-passivation benefiting from their three-dimensional branched structures.
