Check Digit Verification of cas no

The CAS Registry Mumber 98846-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,4 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98846-94:
(7*9)+(6*8)+(5*8)+(4*4)+(3*6)+(2*9)+(1*4)=207
207 % 10 = 7
So 98846-94-7 is a valid CAS Registry Number.

The synthesis of binucleating polyaza macrocyclic and macrobicyclic ligands and the dioxygen affinities of their cobalt complexes

Chen, Dian,Motekaitis, Ramunas J.,Murase,Martell, Arthur E.

, p. 77 - 88 (2007/10/02)

The synthesis of a new macrobicyclic (cryptand) ligand 1,4,9,12,19,20,25,30-octaazabicyclo(10.10.10)dotriacontane, C4BISTREN and improved syntheses of the ligands 7,9,30,trioxa-1,4,10,13,16,22,-27,33-octaazabicyclo(11.11.11)pentatria contane, OBISTREN and 1,13-dioxa-4,7,10,16,19,22-hexaazacyclotetracosane, OBISDIEN. The Co(II) complexes of these ligands are oxygen carriers. Among the six macrocyclic and six macrobicyclic ligands that are considered in this paper, the binuclear cobalt(II) complexes of OBISTREN and OBISDIEN form the most stable dioxygen complexes.
