Check Digit Verification of cas no

The CAS Registry Mumber 89616-73-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,6,1 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 89616-73:
(7*8)+(6*9)+(5*6)+(4*1)+(3*6)+(2*7)+(1*3)=179
179 % 10 = 9
So 89616-73-9 is a valid CAS Registry Number.

Solvent effect on the isotopomerization of Fe(13CO)(CO)(PMe3)2MeI: Implication on the mechanism of CO insertion

Bellachioma, Gianfranco,Cardaci, Giuseppe,Macchioni, Alceo,Reichenbach, Gustavo

, p. 3018 - 3022 (2008/10/08)

The isotopomerization of the Fe(13COa)(COb)(PMe3)2MeI complex was studied in various solvents. The kinetic and thermodynamic parameters suggest that the isotopomerization proceeds via ionization of the Fe-I bond, rearrangement of the formed ion-pair, and reentry of the iodide ligand. This behavior supports a CO insertion mechanism proceeding via direct substitution of the iodide with CO and formation of an ionic intermediate.

Chiral octahedral iron and ruthenium complexes. Use of diastereotopic phosphorus atoms for the direct observation of hidden coupling constants

Pa?kowski, Marek,Chodkiewicz, Wladyslaw,Simonnin, Marie-Paule

, p. 533 - 541 (2008/10/08)

A series of asymmetric phosphorus ligands was synthesized and used to prepare chiral octahedral iron and ruthenium complexes (MR(CO)2L*(PMe3)2)+A -. Their geometrical configuration was deduced from IR and NMR (1H, 31P) spectroscopic studies. Due to the presence of an asymmetric center directly bonded to the metal atom, the two axial PMe3 ligands are shown to be diastereotopic and this allows, for the first time, a direct determination of the phosphorus-phosphorus coupling constants between chemically identical ligands by 31P NMR. The conformation of the asymmetric ligands relative to the other ligands, CO, R, and the two axial PMe3 groups, is shown to be an important factor in determining the magnitude of the proton inequivalence between the two PMe3 ligands.

Reactions of Methyl Complexes of Iron(II) with Lewis Bases

Bellachioma, Gianfranco,Cardaci, Giuseppe,Reichenbach, Gustavo

, p. 2593 - 2598 (2007/10/02)

The ionic complex reacts with Lewis bases (L) to give .Two reaction paths are observed: one involving carbon monoxide insertion followed by attack of the L ligand, and a second in which ligand exchange is followed by an insertion reaction.The relative importance of the two paths depends on the nature and the concentration of L.The neutral complexes also react with Lewis bases to give .When X=I the acetyl complex is readily transformed into the corresponding ionic methyl complex I.The neutral complexes react faster than the ionic ones.The structure of the ionic and neutral complexes has been assigned on the basis of i.r. and n.m.r. evidence.
