Check Digit Verification of cas no

The CAS Registry Mumber 149439-07-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,4,3 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 149439-07:
(8*1)+(7*4)+(6*9)+(5*4)+(4*3)+(3*9)+(2*0)+(1*7)=156
156 % 10 = 6
So 149439-07-6 is a valid CAS Registry Number.

Synthesis and spectroscopic studies of di-s- and t-butyltin(IV) carboxylates

Jain, Vimal K.,Mokal, Vijaya B.

, p. 861 - 864 (2007/10/02)

Di-s- and t-butyltin(IV) carboxylates, xSn(OOCAr)2> (x = sec. or tert.; Ar = C6H5, C6H4OMe-2, 2-C4H3O, 2-C4H3S, 2-C5H4N, 2-C9H6N and 2-C4H3N2) have been prepared and characterized.Carboxylate moiety acts in a bidentate fashion either by coordination through both the oxygen atoms in an asymmetrical manner or chelating through nitrogen in case of ligands containing nitrogen heterocycles.Spectroscopic data (IR and NMR) suggest that these compounds adopt a six-coordinate configuration in solution.
