Check Digit Verification of cas no

The CAS Registry Mumber 670274-23-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,0,2,7 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 670274-23:
(8*6)+(7*7)+(6*0)+(5*2)+(4*7)+(3*4)+(2*2)+(1*3)=154
154 % 10 = 4
So 670274-23-4 is a valid CAS Registry Number.

α,ω-Bis(thioacetyl)oligophenylenevinylene Chromophores from Thioanisol Precursors

Seferos, Dwight S.,Banach, David A.,Alcantar, Norma A.,Israelachvili, Jacob N.,Bazan, Guillermo C.

, p. 1110 - 1119 (2007/10/03)

The selective cleavage of arylmethyl thioethers provides a convenient protocol for the synthesis of all-E isomers of α,ω -bis(thioacetyl)oligophenyenevinylene molecules (OPVs). The S-methyl group is tolerant of Wittig-type and Heck-type reactions for form
