Check Digit Verification of cas no

The CAS Registry Mumber 233584-42-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,3,5,8 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 233584-42:
(8*2)+(7*3)+(6*3)+(5*5)+(4*8)+(3*4)+(2*4)+(1*2)=134
134 % 10 = 4
So 233584-42-4 is a valid CAS Registry Number.

Zr and Hf complexes of bis(phenolate-ether) (“O4”) ligands feature high activity, stereoselectivity and molecular weight capability for propene polymerization at high temperature. Here we report a simplified ligand synthesis and several new examples of O4

Vaulted biaryls in catalysis: A structure-activity relationship guided tour of the immanent domain of the VANOL ligand

Guan, Yong,Ding, Zhensheng,Wulff, William D.

, p. 15565 - 15571 (2013/11/19)

The active site in the BOROX catalyst is a chiral polyborate anion (boroxinate) that is assembled in situ from three equivalents of B(OPh) 3 and one of the VANOL ligand by a molecule of substrate. The substrates are bound to the boroxinate by Hbonds to oxygen atoms O1-O3. The effects of introducing substituents at each position of the naphthalene core of the VANOL ligand are systematically investigated in an aziridination reaction. Substituents in the 4,4′- and 8,8′-positions have a negative effect on catalyst performance, whereas, substituents in the 7- and 7′-positions have the biggest impact in a positive direction. VANOL destination: The active site in the BOROX catalyst is a chiral polyborate anion (boroxinate; see figure) that is assembled in situ from three equivalents of B(OPh)3 and one of the VANOL ligand by a molecule of substrate. The effects of introducing substituents at each position of the naphthalene core of the VANOL ligand are systematically investigated in an aziridination reaction. Copyright

Syntheses of sterically hindered zwitterionic pyridinium phenolates as model compounds in nonlinear optics

Diemer, Vincent,Chaumeil, Helene,Defoin, Albert,Fort, Alain,Boeglin, Alex,Carre, Christiane

experimental part, p. 1767 - 1776 (2009/04/11)

Pyridinium phenolates possess a dissymmetric delocalised π-electron system providing a huge quadratic nonlinearity. They are a promising class of molecules for applications in photoelectronics and photonics. Semiempirical calculations indicate that the interplanar angle between the two aromatic rings leads to enhancement in the NLO properties of these compounds. The confirmation of this feature may be provided by the study of a new series of sterically hindered pyridinium phenolates 2a-e bearing two tert-butyl substituents at the ortho position(s) of the phenolate functionality. Such bulky groups would enhance the solubility of zwitterions in organic solvents and would limit the formation of aggregates. Their efficient preparations by using Suzuki cross-coupling reactions involving 3,5-dialkylated 4-bromopyridine N-oxides are described herein. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.

Formation of hetero-boroxines: Dynamic combinatorial libraries generated through trimerization of pairs of arylboronic acids

Tokunaga, Yuji,Ueno, Hiroki,Shimomura, Youji

, p. 219 - 223 (2008/09/17)

Condensation of pairs of arylboronic acids provided homo- and hetero-boroxines in solution as evidenced from NMR spectra, and those boroxines were detected in the gas phase by GC-MS spectrometry. Equilibrium constants for the formation of these boroxines in solution were obtained through integration of pertinent signals in the NMR spectra of the mixtures ofboronic acids.
