Check Digit Verification of cas no

The CAS Registry Mumber 251452-76-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,4,5 and 2 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 251452-76:
(8*2)+(7*5)+(6*1)+(5*4)+(4*5)+(3*2)+(2*7)+(1*6)=123
123 % 10 = 3
So 251452-76-3 is a valid CAS Registry Number.

Simple synthetic route to soluble polyimides via nitro-displacement reaction and their second-order nonlinear optical properties

Lee Yeong-Beom,Woo, Han Young,Yoon, Chong-Bok,Shim, Hong-Ku

, p. 2345 - 2350 (2007/10/03)

Nonlinear optical (NLO) functionalized polyimides were directly synthesized using the nitro-displacement reaction between an alkanediol monomer and a diimide monomer without a thermal curing step. The polyimides were soluble in aprotic polar solvents such
