Check Digit Verification of cas no

The CAS Registry Mumber 459409-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,9,4,0 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 459409-72:
(8*4)+(7*5)+(6*9)+(5*4)+(4*0)+(3*9)+(2*7)+(1*2)=184
184 % 10 = 4
So 459409-72-4 is a valid CAS Registry Number.

Optical and redox properties of a series of 3,4-ethylenedioxythiophene oligomers

Apperloo, Joke J.,Bert Groenendaal,Verheyen, Hilde,Jayakannan, Manickam,Janssen, Rene A. J.,Dkhissi, Ahmed,Beljonne, David,Lazzaroni, Roberto,Bredas, Jean-Luc

, p. 2384 - 2396 (2007/10/03)

The optical and redox properties of a series of 3,4-ethylenedioxythiophene oligomers (EDOTn, n=1-4) and their β,β'-unsubstituted analogues (Tn, n=1-4) are described. Both series are end capped with phenyl groups to prevent irreversible a-coupling reaction
