Check Digit Verification of cas no

The CAS Registry Mumber 561023-81-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,1,0,2 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 561023-81:
(8*5)+(7*6)+(6*1)+(5*0)+(4*2)+(3*3)+(2*8)+(1*1)=122
122 % 10 = 2
So 561023-81-2 is a valid CAS Registry Number.

Synthesis of bridged oligothiophenes: Toward a new class of thiophene-based electroactive surfactants

Edder, Carine,Frechet, Jean M. J.

, p. 1879 - 1882 (2007/10/03)

(Matrix presented) A series of bridged oligothiophenes have been synthesized. Their novel molecular architecture, comprising two oligothiophenes linked together by a bridge at one α-extremity and one binding group at the other α-extremity, is expected to improve their utility as electroactive surfactants for semiconducting nanoparticles or organic electronics.
