Check Digit Verification of cas no

The CAS Registry Mumber 156264-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,6 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 156264-90:
(8*1)+(7*5)+(6*6)+(5*2)+(4*6)+(3*4)+(2*9)+(1*0)=143
143 % 10 = 3
So 156264-90-3 is a valid CAS Registry Number.

Geometrically-controlled and site-specifically-functionalized phenylacetylene macrocycles

Zhang, Jinshan,Pesak, Douglas J.,Ludwick, James L.,Moore, Jeffrey S.

, p. 4227 - 4239 (2007/10/02)

A convergent, stepwise synthesis of linear phenylacetylene sequences (PASs) is described. The methodology allows for complete control over chain length, sequence order of monomers, and functional group placement. Chain growth follows geometric progression
