Check Digit Verification of cas no
The CAS Registry Mumber 12154-95-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,5 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12154-95:
(7*1)+(6*2)+(5*1)+(4*5)+(3*4)+(2*9)+(1*5)=79
79 % 10 = 9
So 12154-95-9 is a valid CAS Registry Number.

The reaction of [Fe(CO)2(SR)(Cp)] (R=Et, Ph; Cp=η-C5H5) with [Mn(CO)2(thf)(C5H4Me)] (thf=tetrahydrofuran), under photolytic conditions, leads to the formation of the novel heterodinuclear bridged thiolate complexes [FeMn(μ-CO)(μ-SR)(CO)2(Cp)(C5H4Me)] in low yields. [FeMn(μ-CO)(μ-SEt)(CO)2(Cp)(C5H4Me)] consists of a mixture of cis and trans isomers which have been separated and characterized by IR and NMR spectroscopy. The μ-phosphido complex [FeMn(μ-CO)(μ-PPh2)(CO)2(Cp)(C5H 4Me)] has been prepared analogously from [Fe(CO)2(PPh2)(Cp)] and [Mn(CO)2(thf)(C5H4Me)]. Variable temperature NMR spectra of the latter heterodinuclear complex, in CDCl3, show the presence of an equilibrium mixture of the two interconverting cis and -trans isomers. The X-ray molecular structure of cis-[FeMn(μ-CO)(μ-SEt)(CO)2(Cp)(C5H4Me)] shows a bonded Fe-Mn interaction [2.617(2) A] reinforced by a μ-CO and a μ-SEt ligands. The molecule contains chiral centers at the iron, manganese and sulfur atoms and the diastereoisomer under study exhibits optimized non bonded contacts between the alkyl groups.
