Check Digit Verification of cas no

The CAS Registry Mumber 1334479-82-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,4,7 and 9 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1334479-82:
(9*1)+(8*3)+(7*3)+(6*4)+(5*4)+(4*7)+(3*9)+(2*8)+(1*2)=171
171 % 10 = 1
So 1334479-82-1 is a valid CAS Registry Number.

Synthesis and optical properties of pyridino end-capped oligothiophenes

Hwang, Yong-Mook,Ohshita, Joji,Mizumo, Tomonobu,Yoshida, Hiroto,Kunugi, Yoshihito,Sugioka, Takashi

experimental part, p. 1243 - 1247 (2012/01/31)

Oligothiophenes end-capped with fused pyridino units were synthesized by means of the Stille coupling and their optical properties were studied. These compounds show absorption maxima and edges at 324374 nm and 3.102.76 eV, respectively, depending on the oligothiophene chain lengths. DFT calculations indicate that both the HOMO and LUMO levels are lowered by the introduction of the pyridino units.
