Check Digit Verification of cas no
The CAS Registry Mumber 1245-13-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,4 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1245-13:
(6*1)+(5*2)+(4*4)+(3*5)+(2*1)+(1*3)=52
52 % 10 = 2
So 1245-13-2 is a valid CAS Registry Number.

Spectroscopic and electrochemical study of dinuclear and mononuclear copper complexes with the bidentate ligand of the 2,2′-diquinoline series

The newly synthesized complex (2) of copper(I) chloride with di-n-hexyl 2,2'-biquinoline-4,4'-dicarboxylate (L) was spectroscopically and electrochemically characterized. The X-ray diffraction study showed that the crystals of complex 2 consist of the dinuclear moieties [L2Cu 1 2(μ-Cl)2] containing Cu 2(μ-Cl)2 clusters. Spectrophotometric studies and ESI-mass spec-trometric measurements showed that after the dissolution of complex 2 in acetonitrile (AN) and N-methyl-2-pyrrolidone (NMP), the solution contained not only the dinuclear complexes [L2Cu1 2(μ-Cl)2] but also [L2Cu1]Cl, [LCu1Cl(Sol)], and [Cu1Cl(Sol)] (Sol is the solvent). The electrochemical data also confirm the conclusion that bridged dinuclear chloride complex 2 dissociates both in NMP and AN to form the tetrahedral bis-biquinoline complex [L2Cu1]Cl. In solutions of complex 2 in alcohols and N,N-dimethylformamide (DMF), only [L2Cu1]Cl and [Cu1Cl(Sol)] are present. In EtOH, AN, and DMF, [Cu1Cl(Sol)] undergoes disproportionation to [Cu11Cl(Sol)] and Cu0.

The new metal-organic framework [Cd(bqdc)(phen)]n (1) (bqdc = 2, 2'-biquinoline-4, 4'-dicarboxylate, phen = 1, 10-phenanthroline) was hydrothermally synthesized by hetero-ring carboxylate ligand and N-containing auxiliary ligand. The structure of 1 was determined by single-crystal X-ray diffraction analysis and further characterized by elemental analyses, IR spectroscopy, X-ray powder diffraction, and TG analysis. Single-crystal X-ray structural analysis shows that complex 1 is an infinite two-dimensional framework containing aesthetic meso-helix. These two-dimensional coordination networks are interconnected through aromatic π-π stacking and C-H...O hydrogen bonding interactions to afford a 6-connected (412.6 3) three-dimensional supramolecular architecture. Furthermore, the photoluminescent property of complex 1 was studied. Copyright
