230953-49-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 230953-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,0,9,5 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 230953-49:
128 % 10 = 8
So 230953-49-8 is a valid CAS Registry Number.

Synthesis, characterization and magnetic properties of binuclear oxovanadium(IV) complexes with a bromanilate bridge

Li, Yan-Tuan,Yan, Cui-Wei,Xu, Cheng-Shui

, p. 995 - 1007 (1999)

Four novel oxovanadium(IV) binuclear complexes have been synthesized and identified [(VO)2(BA)L2]SO4 [L denotes 2,2'-bipyridine (bpy); 1, 10-phenanthroline (phen); 2,9-dimethyl-1, 10-phenanthroline (Me2-phen) and 5-chloro-1, 10-phenanthroline (Cl-phen), respectively], where BA represents the dianion of bromanilic acid. The complexes were characterized by elemental analyses, molar conductivity and room temperature magnetic moment measurements, IR and electronic spectral studies. Based on these studies, extended BA-bridged structures consisting of two vanadium(IV) ions, each in a square-pyramidal environment, are proposed for these complexes. The complexes [(VO)2(BA)(bpy)2]SO4 (1) and [(VO)2(BA)(phen)2]SO4 (2) were characterized by variable temperature present complexes than that of the complexes [(VO)2(CA)L2]SO4 (L = bpy and phen), so as to increase the antiferromagnetic interaction. This would explain the difference in J values for these complexes.
