Calculate Digit Verification of CAS Registry Number 117131-53:
(8*1)+(7*1)+(6*7)+(5*1)+(4*3)+(3*1)+(2*5)+(1*3)=90
90 % 10 = 0
So 117131-53-0 is a valid CAS Registry Number.

SYNTHESIS AND ELECTROCHEMICAL BEHAVIOUR OF A NEW CLASS OF MACROCYCLIC Li(1+)-SELECTIVE DIAMIDES

Hruska, Zdenek,Petranek, Jaromir

, p. 68 - 75 (2007/10/02)

A series of macrocyclic N-substituted oligomethylenediamides of 4,4,5,5-tetramethyl-3,6-dioxaoctanedioic acid, 5,5-dimethyl-3,7-dioxanonanedioic and trans-1,2-cyclohexanedioxydiacetic acid were prepared.Selectivity of these compounds with respect to the structure of the molecule was investigated electrochemically in polymeric (PVC) membranes of ion-selective electrodes.
