Check Digit Verification of cas no

The CAS Registry Mumber 128508-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,0 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128508-81:
(8*1)+(7*2)+(6*8)+(5*5)+(4*0)+(3*8)+(2*8)+(1*1)=136
136 % 10 = 6
So 128508-81-6 is a valid CAS Registry Number.

2,2'-(2,5-DIHYDROTHIOPHENE-2,5-DIYLIDENE)BIS(1,3-DITHIOLE) DERIVATIVES: NEW EXTENDED ONE-ELECTRON DONORS AND THEIR ELECTROCONDUCTIVE COMPLEXES

Takahashi, Kazuko,Nihira, Takayasu

, p. 5903 - 5906 (2007/10/02)

The tetramethyl and diphenyl derivatives of 2,2'-(2,5-dihydrothiophene-2,5-diylidene)bis(1,3-dithiole) have been isolated as their dication salts, which gave stable radical cations by one-electron reduction.The complexes of new donors with tetracyanoquinodimethan (TCNQ) and iodine showed comparatively high electroconductivities.
