Check Digit Verification of cas no

The CAS Registry Mumber 243653-92-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,3,6,5 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 243653-92:
(8*2)+(7*4)+(6*3)+(5*6)+(4*5)+(3*3)+(2*9)+(1*2)=141
141 % 10 = 1
So 243653-92-1 is a valid CAS Registry Number.

Preparation and redox properties of longitudinally twinned TCNQ: Hexacyanostilbenequinodimethane dianion

Takahashi, Kazuyuki,Kobayashi, Keiji

, p. 5349 - 5352 (1999)

A new extended π-conjugated TCNQ, hexacyanostilbenequinodimethane, was isolated as a dianion salt. Its cyclic voltammograms show that the dianion is reduced reversibly to a trianion radical, while the oxidized species, a monoradical anion, dimerizes to give the dimer dianion, which is further electrochemically oxidized to a neutral polymer.
