197370-02-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197370-02-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,3,7 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 197370-02:
(8*1)+(7*9)+(6*7)+(5*3)+(4*7)+(3*0)+(2*0)+(1*2)=158
158 % 10 = 8
So 197370-02-8 is a valid CAS Registry Number.

Imine-bridged planar poly(phenylenethiophene)s and polythiophenes
Zhang, Qing T.,Tour, James M.
, p. 9624 - 9631 (1997)
Synthetic routes to soluble planar poly(phenylenethiophene)s and polythiophenes are described. The main polymer backbones are synthesized via Pd(0)-catalyzed couplings of the electron-rich N,N'-(bis-tert-butoxycarbonyl)-3,4-diamino-2,5-bis(tri-n- butylsta
