Check Digit Verification of cas no

The CAS Registry Mumber 657412-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,7,4,1 and 2 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 657412-96:
(8*6)+(7*5)+(6*7)+(5*4)+(4*1)+(3*2)+(2*9)+(1*6)=179
179 % 10 = 9
So 657412-96-9 is a valid CAS Registry Number.

Hydrogen Bond-Induced Rigid Oligoanthranilamide Ribbons That Are Planar and Straight

Wu, Zong-Quan,Jiang, Xi-Kui,Zhu, Shi-Zheng,Li, Zhan-Ting

, p. 229 - 232 (2007/10/03)

(Matrix presented) A new series of oligoanthranilamides has been synthesized starting from suitably modified p-phenylenediamine and p-phthalic acid derivatives. Due to strong intramolecular three-center hydrogen bonds, the new oligomers self-assemble into highly stable straight and planar molecular ribbons, which have been characterized by X-ray crystallography and 1H NMR, IR, and UV-vis spectroscopy.
