65639-49-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 65639-49-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,3 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 65639-49:
(7*6)+(6*5)+(5*6)+(4*3)+(3*9)+(2*4)+(1*9)=158
158 % 10 = 8
So 65639-49-8 is a valid CAS Registry Number.

Cyclic ligand control of kinetic lability. Kinetics of dissociation of nickel(II) complexes of a series of O2N2-donor macrocycles in acid

Ekstrom,Lindoy, Leonard F.,Smith, Roland J.

, p. 724 - 727 (1980)

The kinetics of dissociation in acid of a range of nickel complexes of 14-17-membered macrocycles containing an O2N2-donor set has been studied. Macrocycle structure was found to strongly influence the observed first-order dissociation rate constants, and, for the unsubstituted macrocycles, the kinetic labilities follow the ring size sequence 14 > 15 > 16 a number of other ions has also been studied.
