Check Digit Verification of cas no
The CAS Registry Mumber 92390-26-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,3,9 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92390-26:
(7*9)+(6*2)+(5*3)+(4*9)+(3*0)+(2*2)+(1*6)=136
136 % 10 = 6
So 92390-26-6 is a valid CAS Registry Number.

General route to the half-open metallocenes C5Me5Ru(pentadienyl) and C5Me5Ru(diene)Cl. X-ray structures of an optically active half-open metallocene and of a dimetallic ruthenabenzene complex

, p. 2087 - 2098 (2008/10/08)
Treatment of [C5Me5RuCl2]n (1) with various acyclic and cyclic diolefins in the presence of zinc powder leads to the half-open metallocenes C5Me5Ru(pentadienyl), to C5Me5Ru(diolefin) chloro compounds, or to cationic complexes with an η6 ligand, depending on the stereochemistry and substitution pattern of the starting diolefin. An X-ray crystallographic analysis of optically active C5Me5Ru(dimethylnopadienyl) (11; [α]589 = -250.6°), which crystallizes from methanol in the monoclinic space group P21 with a = 9.214 (4) A?, b = 17.593 (8) A?, c = 13.115 (6) A?, β = 101.55 (4)°, and Z = 4, reveals the coordination of the C5Me5Ru moiety from the sterically less hindered side of the tricyclic ligand. The half-open metallocene C5Me5Ru(2,4-C7H11) (2; 2,4-C7H11 = η5-2,4-dimethylpentadienyl) can be protonated with HBF4, yielding [C5Me5Ru(H)(C7H11)]BF4, which has a dynamic structure on the NMR time scale. 2 can also be lithiated; the site of lithiation could be determined by quenching experiments with MeOD/CH3COOD. 2 reacts with [C5H5Ru(CH3CN)3]PF6 to yield the dimetallic complex [C5H5Ru(μ-2,4-C7H9)Ru(C 5Me5)(CH3CN)]PF6 (19). 19 crystallizes from propionic anhydride in the orthorhombic space group Pnma, with a = 13.274 (2) A?, b = 11.865 (2) A?, c = 16.578 (3) A?, and Z = 4 and displays an η6 coordination of a ruthenabenzene unit to C5H5Ru. The substitution of the diolefin and/or chloro ligand in C5Me5Ru(2-methyl-(E)-pentadiene)Cl (7) in a range of solvents and under mild conditions is a rapid and facile process. Mono- and bidentate ligands (Br, CO, CH3, P(OMe)3, cod) substitute the diolefin, the chloro ligand, or both, depending on reaction conditions, to produce the complex C5Me5RuL2X, [C5Me5RuL3]+, or [C5Me5RuL2L′]+. All compounds are obtained in high yield and have been characterized by a combination of elemental analyses and spectroscopic methods (IR, 1H and 13C NMR, MS).
