871123-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871123-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,1,2 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 871123-22:
(8*8)+(7*7)+(6*1)+(5*1)+(4*2)+(3*3)+(2*2)+(1*2)=147
147 % 10 = 7
So 871123-22-7 is a valid CAS Registry Number.

Orthogonal synthesis of poly(aryl ether amide) dendrons
In, Insik,Kim, Sang Youl
, p. 9399 - 9401 (2008/02/01)
A simple orthogonal convergent methodology for the synthesis poly(aryl ether amide) dendrons was introduced. It was found that nucleophilic aromatic substitution and amidation were chosen as orthogonal coupling reactions because each coupling reaction do
