Check Digit Verification of cas no

The CAS Registry Mumber 191917-63-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,9,1 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 191917-63:
(8*1)+(7*9)+(6*1)+(5*9)+(4*1)+(3*7)+(2*6)+(1*3)=162
162 % 10 = 2
So 191917-63-2 is a valid CAS Registry Number.

Protonation and subsequent intramolecular hydrogen bonding as a method to control chain structure and tune luminescence in heteroatomic conjugated polymers

Monkman, Andrew P.,Palsson, Lars-Olof,Higgins, Roger W. T.,Wang, Changsheng,Bryce, Martin R.,Batsanov, Andrei S.,Howard, Judith A. K.

, p. 6049 - 6055 (2002)

We report the effects of protonation on the structural and spectroscopic properties of 1,4-dimethoxy-2,5-bis (2-pyridyl) benzene (9) and the related AB coploymer poly{2,5-pyridylene-co-1,4-[2,5-bis(2-ethylhexyloxy)]phenylene} (7). X-ray crystallographic a
