24867-51-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24867-51-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,6 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24867-51:
(7*2)+(6*4)+(5*8)+(4*6)+(3*7)+(2*5)+(1*1)=134
134 % 10 = 4
So 24867-51-4 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 (1999)

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
