Check Digit Verification of cas no

The CAS Registry Mumber 157771-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,7 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 157771-52:
(8*1)+(7*5)+(6*7)+(5*7)+(4*7)+(3*1)+(2*5)+(1*2)=163
163 % 10 = 3
So 157771-52-3 is a valid CAS Registry Number.

Synthesis and Photophysical Properties of Fluorescent 2-Aryl-1,3-dialkylbenzimidazolium Ions and a 1-Alkyl-2-arylbenzimidazole with Excited State Intramolecular Proton-Transfer

Kauffman, Joel M.,Khalaj, Ali,Litak, Peter T.,Novinski, John A.,Bajwa, Gurdip S.

, p. 957 - 966 (2007/10/02)

To improve the solubility, photostability and fluorescence quantum yield (Φ) of 2-arylbenzimidazolium ions the N-1 hydrogen was replaced by an alkyl group before N-3 was quaternized; this substitution did not reduce Φ, proving the absence of steric inhibi
