Check Digit Verification of cas no

The CAS Registry Mumber 19978-61-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,7 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19978-61:
(7*1)+(6*9)+(5*9)+(4*7)+(3*8)+(2*6)+(1*1)=171
171 % 10 = 1
So 19978-61-1 is a valid CAS Registry Number.

Structurally different mono-, bi- and trinuclear Pd(II) complexes and their DNA/protein interaction, DNA cleavage, and anti-oxidant, anti-microbial and cytotoxic studies

Shanmugapriya,Jain, Ruchi,Sabarinathan,Kalaiarasi,Dallemer,Prabhakaran

, p. 10324 - 10338 (2017)

A series of new structurally different Pd(ii) complexes was obtained by the reactions between K2[PdCl4], 3-methoxysalicylaldehyde-4(N)-substituted thiosemicarbazone [H2L1-H2L4] and bis(diphenylphosphino)ethane [dppe]. All the complexes were characterized by using various spectral techniques (IR, electronic, 1H-NMR and mass spectroscopy). The crystal structures of complexes 1, 3, 4 and 3a & 4a were determined using X-ray crystallographic technique. The interactions of the new complexes with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA) were evaluated using various spectroscopic methods, which showed the interaction potential of the complexes with CT-DNA and BSA. Further, they cleaved supercoiled DNA pBR322. The anti-oxidant profiles of the complexes were found to be better than the standards against 2,2′-diphenyl-1-picrylhydrazyl radicals (DPPH) and superoxide anion radicals. The antibacterial activity of the complexes against five pathogenic bacteria such as Staphylococcus aureus, Salmonella typhi, Escherichia coli, Bacillus subtilis and Pseudomonas aeruginosa was found to be better than their parent ligands. The complexes exhibited potential cytotoxicity against human breast cancer cells (MCF-7) in the following order: 4 > 3 > 1 > cisplatin > 2.

PREPARATION AND REACTIONS OF HYDROXO-ENYLPALLADIUM(II) DERIVATIVES

Rotondo, Enrico,Priolo, Francesca Cusmano,Donato, Andrea,Pietropaolo, Rosario

, p. 273 - 280 (1983)

Some new hydroxo-enyl derivatives of palladium(II) of the type 2, and PF6 (C7H8 = norbornadiene, diene = norbornadiene or 1,5-cyclooctadiene; L-L = 2,2'-dipyridyl or 1,10-phenanthroline) have been made by nucleophilic attack of H2O on the diene coordinated to the metal in dispositively charged complexes.Evidence is presented to show that the hydroxonorbornenyl-1,2-bis(diphenylphosphino)ethane palladium(II) is involved as an intermediate, in an unusual example of oxidation of the alcoholic group through a palladium(II)-mediated intramolecular hydrogen transfer.

The coordination chemistry of sulfonyl-substituted thioureas towards the d8 metal centres platinum(II), palladium(II), nickel(II) and gold(III)

Henderson, William,Risi, Matthew C.,Saunders, Graham C.

, (2021/07/13)

Reactions of the complexes cis-[PtCl2(PPh3)2], [PtCl2(dppp)] (dppp = Ph2P(CH2)3PPh2), [MCl2(dppe)] (dppe = Ph2P(CH2)2PPh2, M = Ni, Pd), [PdCl2(bipy)] (bipy = 2,2′-bipyridine) and [AuCl2(bp)] (bp = cyclometallated 2-benzylpyridine) with p-TolSO2NHC(S)NHPh and Et3N in refluxing methanol gave a series of new thiourea complexes containing the ligand bound as a dianion through the S and the NPh groups. The related thioureas RSO2NHC(S)NHPh (R = Me, Et) and p-TolSO2NHC(S)NHCH2CH=CH2 were also reacted with cis-[PtCl2(PPh3)2] to form the corresponding complexes [Pt{RSO2NC(S)NPh}(PPh3)2] and [Pt{TolSO2NC(S)NCH2CH=CH2}(PPh3)2] respectively. X-ray structure determinations were carried out on the thiourea MeSO2NHC(S)NHPh and its platinum complex [Pt{MeSO2NC(S)NPh}(PPh3)2], as well as [Pt{TolSO2NC(S)NPh}(PPh3)2]. Both complexes form the distal isomer with a remote NSO2R group, and no evidence was observed for isomerisation of these platinum complexes in solution. The palladium complexes [Pd{TolSO2NC(S)NPh}L2] [L2 = Ph2PCH2CH2PPh2 (dppe), or 2,2′-bipyridine (bipy)] undergo decomposition in solution to form the sulfide-bridged aggregates [Pd3S2(L2)3]2+, identified by ESI MS and 31P NMR.

Pyrrole thioamide complexes of the d8 metals platinum(II), palladium(II) and gold(III)

Tang, Haiming,Saunders, Graham C.,Ma, Xiaochuan,Henderson, William

, (2019/12/09)

Reactions of the cycloaurated gold(III) complexes [AuCl2(2-benzylpyridyl)] and [AuCl2(C6H4CH2NMe2)] with a set of pyrrole-2-thioamide ligands, containing various substituents on the pyrrole ring, gave a series of new gold(III) pyrrole thioamide complexes. X-ray crystal structures on two complexes indicate that the pyrrole thioamide ligand is coordinated through the deprotonated pyrrole nitrogen, as well as the sulfur atom of the deprotonated thioamide group, forming five-membered chelate ring complexes. In both complexes, the two highest trans-influence donor atoms (C and S) are mutually cis. Related sets of platinum(II) and palladium(II) pyrrole thioamide complexes were similarly prepared by reactions of cis-[PtCl2(PPh3)2] and [PdCl2(dppe)] (dppe = Ph2PCH2CH2PPh2)] respectively. The complexes were characterised by NMR and IR spectroscopies, and ESI mass spectrometry. A preliminary investigation of the activity of a selection of compounds towards A549 (adenocarcinomic human alveolar basal epithelial) cells was also carried out.

Triphenylene based metal-pyridine cages

Berton, Giacomo,Lorenzetto, Tommaso,Borsato, Giuseppe,Sgarbossa, Paolo,Santo, Claudio,Visentin, Fabiano,Fabris, Fabrizio,Scarso, Alessandro

supporting information, (2019/10/02)

C3-symmetric pyridine containing tris-benzyl-O-substituted hexahydroxytriphenylene derivatives were prepared and used in combination with square-planar Pd(II) and Pt(II) complexes for the self-assembly of molecular cages in solution. The formation of a trigonal bipyramid M3L2 cage was demonstrated by multinuclear NMR analyses and pseudo 2D DOSY experiments and supported by semi-empirical calculations.
