Check Digit Verification of cas no

The CAS Registry Mumber 97546-23-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,5,4 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 97546-23:
(7*9)+(6*7)+(5*5)+(4*4)+(3*6)+(2*2)+(1*3)=171
171 % 10 = 1
So 97546-23-1 is a valid CAS Registry Number.

Synthesis of new lipophilic acyclic di-ionizable polyethers, bis(crown ethers) and macrocyclic diamides

Elshani, Sadik,Wai, Chien M.,Natale,Bartsch, Richard A.

, p. 9425 - 9438 (2007/10/03)

A series of new lipophilic acyclic polyethers containing two carboxylic or hydroxamic acid groups have been prepared. From lipophilic acyclic polyether dicarboxylic acids 2, 9 and 13, the bis(crown ethers) 20-25 were synthesized. From lipophilic acyclic polyether dicarboxylic acids 10-12 and 14, the new macrocyclic diamides 26-32 were prepared in high yields without the use of high dilution techniques or template effects.
