Check Digit Verification of cas no

The CAS Registry Mumber 1048-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,4 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1048-08:
(6*1)+(5*0)+(4*4)+(3*8)+(2*0)+(1*8)=54
54 % 10 = 4
So 1048-08-4 is a valid CAS Registry Number.

Hypervalent silicon hydrides: evidence for their intermediacy in the exchange reactions of di- and tri-hydrogenosilanes catalysed by hydrides (NaH, KH and LiAlH4)

Becker, B.,Corriu, R. J. P.,Guerin, C.,Henner, B. J. L.

, p. 147 - 154 (1989)

Di and tri-hydrogenosilanes, RR'SiH2 and RSiH3 (R=aryl, allyl or benzyl; R'=aryl or alkyl), readily undergo exchange reactions, involving silicon-carbon bonds and silicon-hydrogen bonds, in the presence of hydrides (LiAlH4, KH and NaH) as catalysts.These results are discussed in terms of five-coordinate silicon hydrides as intermediates in the reaction.

Disproportionation reactions of organohydrosilanes in the presence of base catalysts

Itoh, Masayoshi,Inoue, Koji,Ishikawa, Jun-Ichi,Iwata, Kenji

, p. 1 - 6 (2001)

Alkoxides, alkyl compounds, amides and hydrides of alkali metals (M) and barium, such as MOR, Ba(OR)2, n-BuM, PhM, MN(SiMe3)2 and MAlH4 showed high catalytic activities versus the disproportionation reactions of PhSiH3 to produce SiH4, Ph2SiH2 and Ph3SiH. A good correlation between the catalyst basicities and the catalytic activities was observed, and a reaction mechanism involving the metal hydride and alkyl metal was proposed. A considerable amount of SiH4 was produced in the reduction of PhSiCl3 with LiAlH4 when over three moles of LiAlH4 was used.

A well-defined NHC-Ir(III) catalyst for the silylation of aromatic C-H bonds: Substrate survey and mechanistic insights

Rubio-Pérez, Laura,Iglesias, Manuel,Munárriz, Julen,Polo, Victor,Passarelli, Vincenzo,Pérez-Torrente, Jesús J.,Oro, Luis A.

, p. 4811 - 4822 (2017/07/11)

A well-defined NHC-Ir(iii) catalyst, [Ir(H)2(IPr)(py)3][BF4] (IPr = 1,3-bis-(2,6-diisopropylphenyl)imidazol-2-ylidene), that provides access to a wide range of aryl- and heteroaryl-silanes by intermolecular dehydrogenative C-H bond silylation has been prepared and fully characterized. The directed and non-directed functionalisation of C-H bonds has been accomplished successfully using an arene as the limiting reagent and a variety of hydrosilanes in excess, including Et3SiH, Ph2MeSiH, PhMe2SiH, Ph3SiH and (EtO)3SiH. Examples that show unexpected selectivity patterns that stem from the presence of aromatic substituents in hydrosilanes are also presented. The selective bisarylation of bis(hydrosilane)s by directed or non-directed silylation of C-H bonds is also reported herein. Theoretical calculations at the DFT level shed light on the intermediate species in the catalytic cycle and the role played by the ligand system on the Ir(iii)/Ir(i) mechanism.

Efficient preparation of monohydrosilanes using palladium-catalyzed Si-C bond formation

Yamanoi, Yoshinori,Taira, Takafumi,Sato, Jun-Ichi,Nakamula, Ikuse,Nishihara, Hiroshi

, p. 4543 - 4546 (2008/03/13)

(Chemical Equation Presented) The arylation of dihydrosilanes with aryl iodides or heteroaryl iodides in the presence of a palladium catalyst provides the corresponding monohydrosilanes in good to high yield. Moderate to good yields are obtained even in the presence of a variety of reactive functional groups, such as -NH2, -OH, or -CN, without their protection.
