Check Digit Verification of cas no

The CAS Registry Mumber 856045-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,6,0,4 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 856045-97:
(8*8)+(7*5)+(6*6)+(5*0)+(4*4)+(3*5)+(2*9)+(1*7)=191
191 % 10 = 1
So 856045-97-1 is a valid CAS Registry Number.

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
