Check Digit Verification of cas no
The CAS Registry Mumber 138536-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,3 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138536-47:
(8*1)+(7*3)+(6*8)+(5*5)+(4*3)+(3*6)+(2*4)+(1*7)=147
147 % 10 = 7
So 138536-47-7 is a valid CAS Registry Number.

MACROCYCLIC Li+-SELECTIVE DIAMIDES
Hruska, Zdenek,Petranek, Jaromir
, p. 2154 - 2159 (2007/10/02)
Several macrocyclic diamides of 4,4,5,5-tetramethyl-3,6-dioxaoctanedioic acid with various N-alkyl substituents have been prepared.Selectivity of these compounds was investigated electrochemically in polymeric (PVC) membranes of ion-selective electrodes.
