Check Digit Verification of cas no
The CAS Registry Mumber 673458-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,3,4,5 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 673458-28:
(8*6)+(7*7)+(6*3)+(5*4)+(4*5)+(3*8)+(2*2)+(1*8)=191
191 % 10 = 1
So 673458-28-1 is a valid CAS Registry Number.

Synthesis and Reactivity of a 1,8-Bis(methylium)naphthalenediyl Dication
Wang, Huadong,Gabbai, Francois P.
, p. 184 - 187 (2004)
A voracious appetite for electrons is displayed by the 1,8-bis(methylium)naphthalenediyl dication (see picture). Cooperative effects arising from the proximity of the methylium centers intensify the electron affinity of this molecule and make it very sens
