Check Digit Verification of cas no

The CAS Registry Mumber 86731-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,7,3 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86731-50:
(7*8)+(6*6)+(5*7)+(4*3)+(3*1)+(2*5)+(1*0)=152
152 % 10 = 2
So 86731-50-2 is a valid CAS Registry Number.

Synthesis and decomplexation of (η-arene)(η-cyclopentadienyl)iron(II) hexafluorophosphates using microwave dielectric heating

Dabirmanesh, Qumars,Fernando, Sharon I. S.,Roberts, Roger M. G.

, p. 743 - 750 (2007/10/02)

A detailed study of the synthesis of (η-arene)(η-cyclopentadienyl)iron(II) hexafluorophosphates has been made using microwave dielectric heating.Reactions were carried out in a coventional 850 W microwave oven in a very simple solid CO2-cooled apparatus.A wide range of arene ligands were used.The microwave technique reduced the normal reaction times for the AlCl3-mediated ligand exchange with ferrocene (with aluminium powder to prevent ferricinium ion formation) from several hours to a few minutes and generally resulted in higher yields. 1,2,4-Trichlorobenzene was found to be an axcellent solvent for such reactions.A preliminary survey of the efficacy of the type of the metal powder used revealed that zinc and copper were as effective as aluminium, but that nickel and tin gave little or no reaction.Better yields were usually obtained when an excess of ferrocene was used.This was particularly true of alkylarene ligands where almost quantitative yields were obtained in some cases.The microwave method is particularly suited to the synthesis of bis and more highly complexed species.Arylamine complexes can also be made in high yields.Complexes of triphenylphosphine are reported together with a wide range of other arenes.Decomplexation of these complexes can be efficiently achieved by a slight variant of the above microwave procedure.High yields of free ligand were obtained by irradiating an admixture of the complexes with flaked graphite.

THE SYNTHESIS OF SOME η6-KETOARENE-η5-CYCLOPENTADIENYLIRON CATIONS AND THEIR REDUCTION WITH SODIUM BOROHYDRIDE

Lee, C. C.,Demchuk, K. J.,Gill, U. S.,Sutherland, R. G.

, p. 71 - 80 (2007/10/02)

η6-Ketoarene-η5-cyclopentadienyliron cations were prepared from KMnO4 oxidation of the aqueous solution of the tetrachloroaluminate salts of η6-arene-η5-cyclopentadienyliron cations derived from ligand exchange
