Check Digit Verification of cas no

The CAS Registry Mumber 1779-25-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,7 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1779-25:
(6*1)+(5*7)+(4*7)+(3*9)+(2*2)+(1*5)=105
105 % 10 = 5
So 1779-25-5 is a valid CAS Registry Number.

Effect of crystallization water and nature of an aluminum alkyl on the reduction of Eu3+ to Eu2+ in interaction of EuCl 3 ? 6H2O with Bu 3 i Al and Et3Al

Bulgakov,Kuleshov,Makhmutov

, p. 1342 - 1345 (2009)

Volumetric and photoluminescence analytical techniques were employed to study the effect of crystallization water and nature of an aluminum alkyl on the reduction of Eu3+ to Eu2+ in a heterophase interaction of EuCl3 ? 6H

Alkylaluminum-complexed zirconocene hydrides: Identification of hydride-bridged species by NMR spectroscopy

Baldwin, Steven M.,Bereaw, John E.,Brintzinger, Hans H.

, p. 17423 - 17433 (2009/06/08)

Reactions of unbridged zirconocene dichlorides, (RnC 5H5-n)2ZrCl2 (n=0, 1, or 2), with diisobutylaluminum hydride (HAI'Bu2) result in the formation of tetranuclear trihydride clusters of the type (RnC5H 5-n)2Zr(μ-H)3(Al iBu2)3(μ-CI) 2, which contain three [Al iBu2] units. Ring-bridged ansa-zirconocene dichlorides, Me2E(RnC5H 4-n)2ZrCl2 with E=C or Si, on the other hand, are found to form binuclear dihydride complexes of the type Me2E(R nC5H4-n)2Zr(CI)(μ-H) 2Al iBu2 with only one [AIBu2] unit. The dichotomy between unbridged and bridged zirconocene derivatives with regard to tetranuclear versus binuclear product formation is proposed to be connected to different degrees of rotational freedom of their C5-ring ligands. Alkylaluminum-complexed zirconocene dihydrides, previously observed in zirconocene-based precatalyst systems activated by methylalumoxane (MAO) upon addition of HAI'Bu2 or Al iBu3, are proposed to be species of the type Me2Si(ind)2Zr(Me)(μ-H) 2Al iBu2, stabilized by interaction of their terminal Me group with a Lewis acidic site of MAO.

Activation of alkylidene-bridged heterobimetallic complexes toward electrophilic attack

Clift, Susan M.,Schwartz, Jeffrey

, p. C5-C8 (2007/10/02)

Treatment of alkylidene-bridged zirconium-aluminum species with HMPA renders the CAl bond of the alkylidene unit susceptible to electrophilic attack; in the absence of HMPA, the CZr bond is attacked.
