Check Digit Verification of cas no

The CAS Registry Mumber 14090-87-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14090-87:
(7*1)+(6*4)+(5*0)+(4*9)+(3*0)+(2*8)+(1*7)=90
90 % 10 = 0
So 14090-87-0 is a valid CAS Registry Number.

Electron Ionization Mass Spectrometry of Systematically Modified Ligands in Chromium(III) β-Diketonates

Schultze, Peter,Wenclawiak, Bernd W.

, p. 235 - 240 (1989)

The positive ion mass spectra of several chromium(III) β-diketonates with aliphatic α-substituents have been investigated.Metastable peaks in the spectra confirm that ions containing substituents with γ-H atoms undergo propene loss.This implies a McLafferty rearrangement of an open-chain ligand stucture.Ethyl radicals are lost from n-butyl substituents;methyl groups are cleaved from the molecular ions of complexes formed from methyl-substituted ligands.The main fragment is, as expected, 2>+; however, its further fragmentation is diffewrent from that of 3>+.Electron donating substituents stabilize doubly charged molecular ions.

Highly atom-efficient oxidation of electron-deficient internal olefins to ketones using a palladium catalyst

Mitsudome, Takato,Yoshida, Syuhei,Mizugaki, Tomoo,Jitsukawa, Koichiro,Kaneda, Kiyotomi

, p. 5961 - 5964 (2013/06/27)

A 100 % atom-efficient synthesis of ketones from electron-deficient internal olefins was achieved using O2 as a "green" oxidant (see scheme, DMA=N,N-dimethylacetamide, EWG=electron-withdrawing group). Various electron-deficient olefins were oxidized to the corresponding ketones with over 99 % selectivity and without the formation of olefin isomers or their oxidized products. Copyright

Synthesis and characterization of polycarbonyl compounds via their BF 2-adducts

Kersten, Laura,Roesner, Stefan,Hilt, Gerhard

scheme or table, p. 4920 - 4923 (2010/12/25)

A cobalt-catalyzed 1,4-hydrovinylation reaction is the key step in the synthesis of 1,3-dicarbonyl and higher tri- and tetracarbonyl compounds after ozonolysis of the 1,4-diene intermediates. For the isolation and characterization of the products, the 1,3-dicarbonyl subunits were complexed with a BF2- or a BR2-fragment eliminating the keto-enol tautomerisation. Other 2,3-disubstituted 1,3-butadienes can be generated by a Grubbs enyne metathesis of a symmetrical internal alkyne with ethene. After hydrovinylation and ozonolysis, other 1,3-diketones are accessible.

Asymmetric hydrogenation method of a ketonic compound and derivative

-

, (2008/06/13)

The present invention relates to a process for the asymmetric hydrogenation of a ketonic compound and derivative. The invention relates to the use of optically active metal complexes as catalysts for the asymmetric hydrogenation of a ketonic compound and derivative. The process for the asymmetric hydrogenation of a ketonic compound and derivative is characterized in that the asymmetric hydrogenation of said compound is carried out in the presence of an effective amount of a metal complex comprising as ligand an optically active diphosphine corresponding to one of the following formulae: STR1
