Check Digit Verification of cas no

The CAS Registry Mumber 1266615-51-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,6,6,1 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1266615-51:
(9*1)+(8*2)+(7*6)+(6*6)+(5*6)+(4*1)+(3*5)+(2*5)+(1*1)=163
163 % 10 = 3
So 1266615-51-3 is a valid CAS Registry Number.

Spectroscopic studies on the interaction of cilostazole with iodine and 2,3-dichloro-5,6-dicyanobenzoquinone

Pandeeswaran,El-Mossalamy,Elango

scheme or table, p. 375 - 382 (2011/03/21)

The electron accepting properties of the 2,3-dichloro-5,6- dicyanobenzoquinone and iodine and electron donating properties of the drug cilostazole have been studied using the UV-vis, FT-IR, GC-MS and Far-IR techniques. The interaction of cilostazole drug with iodine and 2,3-dichloro-5,6-dicyanobenzoquinone resulted via the initial formation of charge-transfer complex as an intermediate. The rate of formation of the product have been measured and discussed as a function of solvent and temperature. The complexes have been found by Job's method of continuous variation revealed that the stoichiometry of the complexes in both the cases was 1:1. The enthalpies and entropies of formation of the complexes have been obtained by determining their rate constant at three different temperature. The ionization potential of the donor was determined using the charge-transfer absorption bands of the complexes and the same was found comparable with that computed using MOPAC PM3 method.
