Check Digit Verification of cas no

The CAS Registry Mumber 688744-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,8,7,4 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 688744-97:
(8*6)+(7*8)+(6*8)+(5*7)+(4*4)+(3*4)+(2*9)+(1*7)=240
240 % 10 = 0
So 688744-97-0 is a valid CAS Registry Number.

The Water-Exchange Rate in Neutral Heptadentate DO3A-Like GdIII Complexes: Effect of the Basicity at the Macrocyclic Nitrogen Site

Terreno, Enzo,Boniforte, Patrizia,Botta, Mauro,Fedeli, Franco,Milone, Luciano,Mortillaro, Armando,Aime, Silvio

, p. 3530 - 3533 (2007/10/03)

The rate of exchange of the two water molecules coordinated to a Gd III centre in neutral complexes with heptadentate DO3A derivatives is modulated by the basicity of the macrocyclic nitrogen bearing the pendant group: a lower basicity results
