21726-23-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21726-23-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,2 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21726-23:
(7*2)+(6*1)+(5*7)+(4*2)+(3*6)+(2*2)+(1*3)=88
88 % 10 = 8
So 21726-23-8 is a valid CAS Registry Number.

Synthesis and properties of novel fluorinated polyamides based on 2-trifluoromethyl-4,4′-diaminodiphenylether

Yang, Chin-Ping,Chen, Ruei-Shin,Chen, Kuei-Hung,Chen, Ya-Ping

, p. 927 - 934 (2002)

A series of soluble fluorinated polyamides (4a-h) were synthesized from 2-trifluoromethyl-4,4′-diaminodiphenylether (2) with various aromatic diacids (3a-c) and imide-containing diacids (3d-h) via direct polycondensation with triphenyl phosphite and pyrid

Enhanced redox stability and electrochromic properties of aromatic polyamides based on N,N-bis(4-carboxyphenyl)-N′,N′-bis(4-tert- butylphenyl)-1,4-phenylenediamine

Wang, Hui-Min,Hsiao, Sheng-Huei

experimental part, p. 337 - 351 (2012/01/12)

A new bis(triphenylamine)-type dicarboxylic acid monomer, N,N-bis(4-carboxyphenyl)-N′,N′-bis(4-tert-butylphenyl)-1, 4-phenylenediamine, was prepared by a well-established procedure and led to a new family of redox-active aromatic polyamides with di-tert-b
