Check Digit Verification of cas no

The CAS Registry Mumber 1612889-93-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,8,8 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1612889-93:
(9*1)+(8*6)+(7*1)+(6*2)+(5*8)+(4*8)+(3*9)+(2*9)+(1*3)=196
196 % 10 = 6
So 1612889-93-6 is a valid CAS Registry Number.

Random poly(3-hexylthiophene-co-3-cyanothiophene) copolymers with high open-circuit voltage in organic solar cells

Khlyabich, Petr P.,Rudenko, Andrey E.,Thompson, Barry C.

, p. 1055 - 1058 (2014)

Four novel random poly(3-hexylthiophene) copolymers containing 5-20% of 3-cyanothiophene are synthesized by Stille polycondensation; and their electrochemical, optical, charge transport, and photovoltaic properties are investigated. All polymers show high efficiencies and high open-circuit voltages (Voc) up to 0.81 V with a PC61BM acceptor in organic solar cells. Copyright
