197144-71-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197144-71-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,1,4 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 197144-71:
(8*1)+(7*9)+(6*7)+(5*1)+(4*4)+(3*4)+(2*7)+(1*1)=161
161 % 10 = 1
So 197144-71-1 is a valid CAS Registry Number.

Syntitesis and redox properties of sterically hindered meta- and para-Aminophosphinobenzenes
Sasaki, Shigeru,Murakami, Fumiki,Yoshifuji, Masaaki
, p. 7095 - 7098 (1997)
Meta- and para- aminophosphinobenzenes composed of para substituted triarylamine and all ortho methylated triarylphosphine moieties were synthesized and their redox properties were investigated by cyclic voltammetry.
