Check Digit Verification of cas no

The CAS Registry Mumber 615252-25-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,5,2,5 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 615252-25:
(8*6)+(7*1)+(6*5)+(5*2)+(4*5)+(3*2)+(2*2)+(1*5)=130
130 % 10 = 0
So 615252-25-0 is a valid CAS Registry Number.

Synthesis and characterization of N-(o-vanillinidene)-p-anisidine and N,N′-bis(o-vanillinidene)ethylenediamine and their metal complexes

Maurya,Patel,Rajput

, p. 817 - 836 (2008/10/08)

Two Schiff bases, N-(o-vanillinidene)-p-anisidine (o-VPAH) and N,N′-bis(o-vanillinidene)ethylenediamine (o-VEDH2), and eleven complexes of the compositions [M(L)(OAc)(H2O)] {where M = Cu(II) (1), Co(II) (2), Mn(II) (3) or Ni(II) (4) and OAcH = CH3COOH}, [Zn(L)2]·H2O (5), [M(L′)(H2O)2] {where M = Cu(II) (6) or Ni(II) (7)}, [Zn(L′)]·2H2O (8), [Sm(L′)(OAc)(H2O)] (9), [Th(L′)(NO3)2] (10) and [UO2(L′)(H2O)]· H2O (11) (where LH = o-VPAH, and L′H2 = o-VEDH2), were prepared. From the elemental analyses, IR, electronic and NMR spectra, magnetic susceptibility measurements and thermal studies, the mode of chelation of the ligands and geometry of the complex molecules were assigned. In all of the complexes, o-VPAH acts as a monobasic-bidentate ligand and o-VEDH2 acts as a dibasic-tetradentate ligand. The presence of water is revealed by thermograms and supported by the presence of relevant bands in their IR spectra. Suitable structures have been proposed for these complexes.
