Check Digit Verification of cas no
The CAS Registry Mumber 758-21-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 758-21:
(5*7)+(4*5)+(3*8)+(2*2)+(1*1)=84
84 % 10 = 4
So 758-21-4 is a valid CAS Registry Number.

Reactions of diruthenium tetrahydride complex (η5-C5Me5)Ru(μ-H)4 Ru(η5-C5Me5) with vinylsilanes: Formation of a μ-silylene complex via successive Si-H and Si-C bond cleavage of dimethylvinylsilane

The diruthenium complex {Cp*Ru(μ-H)}2{μ-η2:η2- HSiMe2(CH=CH2)} (5a; Cp* = η5-C5-Me5) containing a μ-vinylsilane ligand was prepared by the reaction of Cp*Ru(μ-H)4RuCp* (1) with dimethylvinylsilane. The μ-η2:η2-coordination mode of dimethylvinylsilane was confirmed by means of 1H, 13C, and 29Si NMR and IR spectroscopy. The Si-C(sp2) bond of 5a was readily cleaved upon thermolysis with liberating hydrogen and resulted in formation of the μ-silylene, μ-ethylidyne complex (Cp*Ru)2(μ-SiMe2)(μ-CCH3)(μ-H) (8) via the μ-sily μ-vinyl complex (Cp*Ru)2(μ-η2-HSiMe2) (μ-η2-CH=CH2) (9a) as an intermediate. The reaction of 1 with trimethylvinylsilane rendered cleavage of both Si-C(sp2) and Si-C(sp3) bonds, which resulted in formation of 8. Treatment of 8 with carbon monoxide led to formation of the μ-ethylidene complex by migration of the hydride to the bridging carbon; thus {Cp*Ru-(CO)}2(μ-CHMe)(μ-SiMe2) (10) was obtained. The reaction of 8 with ethylene afforded the μ-vinyl, μ-silylene complex (Cp*Ru)2(μ-η2-CH=CH2) (μ-SiMe2)(μ-H) (CH2=CH2) (11). The reaction of 8 with molecular hydrogen resulted in a re-formation of 1 with liberating dimethylethylsilane, which showed formation of the Si-C bond on the dinuclear system. The molecular structures of 5a, 8, and 10 were determined by single-crystal X-ray diffraction studies.
