Check Digit Verification of cas no

The CAS Registry Mumber 14543-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,5,4 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 14543-09:
(7*1)+(6*4)+(5*5)+(4*4)+(3*3)+(2*0)+(1*9)=90
90 % 10 = 0
So 14543-09-0 is a valid CAS Registry Number.

Aluminum halide-cobalt halide polynuclear complexes active in low-temperature conversion of alkanes: Formation, molecular structures, and IR spectra

Compression behavior of the delafossite-type metallic oxide PdCoO 2 below 10 GPa

Hasegawa,Tanaka,Yagi,Takei,Inoue

, p. 303 - 307 (2003)

The compression behavior of delafossite-type metallic oxide PdCoO 2 below 10 GPa has been investigated by in situ high pressure X-ray diffraction measurement using synchrotron radiation. It is found that the delafossite-type structure of PdCoO2 is stable below 10 GPa. It should be noted that compression behavior of PdCoO2 is anisotropic. Pressure dependence of the lattice parameters indicates that the a-axis is more compressible than the c-axis. The lattice parameter ratio c/a in the hexagonal unit increases with increasing pressure. The calculated zero-pressure bulk modulus is 224 GPa. It is found that the above characteristic compression behaviors of PdCoO2 are the same as those of the delafossite CuFeO2. The compressibilities of the a-axis of both PdCoO 2 and CuFeO2 are highly different although those of the c-axis are almost the same.

Benzyl alcohol-based synthesis of oxide nanoparticles: The perspective of SN1 reaction mechanism

Hu, Mingjun,Xu, Jiaju,Gao, Jiefeng,Yang, Shiliu,Wong, Julia Shuk Ping,Li, Robert K. Y.

, p. 9777 - 9784 (2013)

In this paper, we describe a class of benzyl alcohol-based reactions for the synthesis of a series of inorganic oxide nanoparticles. Benzyl alcohol served as both the solvent and the reagent to interact with various metal chlorides for the synthesis of a series of metal oxides and compound oxides. Typical metal(iv) oxides, like TiO2, metal(iii) oxides, like Fe 2O3, and metal(ii) oxides, like ZnO, with uniform size and special dispersibility, have been prepared through these reactions. The reaction can be illustrated from the perspective of SN1 reaction mechanism attributed to the easier formation of benzyl carbocation and unique reactivity of benzyloxy group with nucleophilic agents. By adjusting the experimental conditions, it was found that this type of reaction is available for the synthesis of many inorganic oxides. The Royal Society of Chemistry 2013.

New complexes of 4-[(4-fluorophenyl)amino]-4-oxobut-2-enoic acid with selected transition metal ions: Synthesis, thermal, and magnetic properties

Ferenc,Sadowski,Tarasiuk,Cristóv?o,Osypiuk,Sarzyński

, p. 2719 - 2727 (2017)

Complexes of 4-[(4-fluorophenyl)amino]-4-oxobut-2-enoic acid, HL, with Mn(II), Co(II), Ni(II), Cu(II), Nd(III), Gd(III), and Er(III) were synthesized and characterized by various physico-chemical methods: elemental analysis, FT-IR, TG, DTG, DSC, TG/FT-IR, XRF, XRD, and magnetic measurements using the Gouy’s method and a SQUID-VSM magnetometer. The complexes were found to be hydrates (except Er(III) complex) containing 1 to 4 molecules of water. The carboxylate groups acted as bidentate ligands.

Mixed-Ligand Cobalt(III) Complexes of a Naturally Occurring Coumarin and Phenanthroline Bases as Mitochondria-Targeted Dual-Purpose Photochemotherapeutics

Hussain, Akhtar,Kumar, Arun,Sahoo, Somarupa,Sarkar, Tukki

, p. 6649 - 6662 (2021)

The bioessential nature of cobalt and the rich photochemistry of its coordination complexes can be exploited to develop potential next-generation photochemotherapeutics. A series of six novel mixed-ligand cobalt(III) complexes of the formulation [Co(B)2(L)]ClO4 (1-6), where B is an N,N-donor phenanthroline base, namely, 1,10-phenanthroline (phen in 1 and 4), dipyrido[3,2-d:2′,3′-f]quinoxaline (dpq in 2 and 5), and dipyrido[3,2-a:2′,3′-c]phenazine (dppz in 3 and 6), and L is an O,O-donor dianionic ligand derived from catechol (1,2-dihydroxybenzene, cat2-, in 1-3) or esculetin (6,7-dihydoxycoumarin, esc2-, in 4-6), have been prepared and characterized, and their light-triggered cytotoxicity has been studied in cancer cells. The single-crystal X-ray diffraction structures of complexes 1 (as PF6- salt, 1a) and 2 show distorted octahedral geometries around the cobalt(III) center formed by the set of N4O2 donor atoms. The low-spin and 1:1 electrolytic complexes 1-6 display a d-d transition around 700 nm. Complexes 4-6 with a coordinated esc2- ligand additionally display a π→ π? intraligand transition centered at 403 nm. Complexes 4-6 possessing a naturally occurring and photoactive esc2- ligand show high visible-light-triggered cytotoxicity against HeLa and MCF-7 cancer cells, yielding remarkably low micromolar IC50 values while being much less toxic under dark conditions. Control complexes 1-3 possessing the photoinactive cat2- ligand show significantly less cytotoxicity either in the presence of light or in the dark. The complex-induced cell death is apoptotic in nature caused by the formation of reactive oxygen species via a type 1 photoredox pathway. Fluorescence microscopy of HeLa cells treated with complex 6 reveals mitochondrial localization of the complex. A significant decrease in the dark toxicity of free esculetin and dppz base is observed upon coordination to cobalt(III). Complexes bind to calf-thymus DNA with significant affinity, but 6 binds with the greatest affinity. Complex 6 efficiently photocleaves supercoiled DNA to its nicked circular form when irradiated with visible light via a photoredox type 1 pathway involving hydroxyl radicals (HO?). Thus, complex 6 showing remarkable visible-light-triggered cytotoxicity but negligible toxicity in the dark is a good candidate for cancer photochemotherapy applications.

Ground Term Splitting of High-Spin Co(2+) as a Probe of Coordination Structure. 1. Dependence of the Splitting on Coordination Geometry

Makinen, Marvin W.,Kuo, Lawrence C.,Yim, Moon B.,Wells, Gregg B.,Fukuyama, James M.,Kim, Judy E.

, p. 5245 - 5255 (1985)

The sign and magnitude of the splitting between the two lowest Kramers doublets (Δ) of high-spin Co(2+) in a variety of structurally defined, small molecule coordination complexes is determined.The range of values of Δ is found to be -1 in tetracoordinate sites, ca. 20-50 cm-1 in pentacoordinate sites of trigonal-bipyramidal or square-pyramidal geometry, and 50 cm-1 in hexacoordinate sites.It is shown on the basis of group theoretical arguments and estimates of the zero-field splitting derived by second-order perturbation theory that the observed range of values of Δ correlates well with that predicted by theory.On this basis, it is suggested that the splitting between the two lowest Kramers doublets of high-spin Co(2+) may provide a diagnostic signature of coordination geometry.

Molecular complexes of cobalt(II) and Zinc(II) chlorides and bromides with 1-piperidinyl dimethylcarbamodithioate (L): Crystal structures of L and [ZnLBr2]

Seifullina,Khitrich,Vologzhanina

, p. 184 - 189 (2011)

Complexes of MX2(M = Co, Zn; X = Cl, Br) with 1-piperidinyl dimethylcarbamodithioate (L) of composition [MLX2] have been synthesized. The compounds have been studied by elemental analysis; X-ray diffraction; thermogravimetry; conductometry; magnetochemistry; and IR, 1H NMR, and electronic absorption spectroscopy. The ligand molecule is coordinated to the metal atoms in a bidentate chelating mode through the thione sulfur atom and the sulfenamide nitrogen atom to form a five-membered chelate ring. The structures of L and [ZnLBr2] have been determined by X-ray crystallography.
