Check Digit Verification of cas no

The CAS Registry Mumber 1145-98-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,4 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1145-98:
(6*1)+(5*1)+(4*4)+(3*5)+(2*9)+(1*8)=68
68 % 10 = 8
So 1145-98-8 is a valid CAS Registry Number.

Photoinduced reductive coupling of organochlorosilanes with SmI2/Sm

Yoshimura, Aya,Tomisaka, Yuri,Li, Zhifang,Nomoto, Akihiro,Ogawa, Akiya

, p. 684 - 689 (2014)

We report efficient reductive dimerization of chlorosilanes with SmI2/Sm in 1,2-dimethoxyethane upon visible light irradiation. This procedure can be applied to the synthesis of polysilanes from dichlorosilanes. The molecular weight of the obtained polysilanes was higher and their molecular weight distribution was narrower than the polysilanes produced by reactions with SmI2/Sm in dark.

Electrolytic Behavior of Iodo- and Chlorosilanes. The Formation of Si-Si and Si-sp-C Bonds

Kunai, Atsutaka,Ohnishi, Osamu,Sakurai, Tomohiro,Ishikawa, Mitsuo

, p. 1051 - 1052 (1995)

Electrolysis of iodosilanes with Al/Pt electrodes in pivalonitrile results in the formation of the Si-Si bonds to give the corresponding disilanes.On the other hand, the electrolysis of various halosilanes such iodo-, chloro-, and fluorosilanes with Pt/Pt electrodes in the presence of phenylacetylene leads to the formation of the Si-sp-carbon bonds to give phenylethynylated products.

Reductive elimination of cis-bis(phenyldimethylsilyl)bis(phosphine)platinum(II) complexes was found to occur to give sym-diphenyltetramethyldisilane together with redistribution by-products.Addition of free phosphine was favorable for the reductive elimin

Electroreductive Formation of Polysilanes

Shono, Tatsuya,Kashimura, Shigenori,Ishifune, Manabu,Nishida, Ryoichi

Electroreduction of dichlorosilanes, such as 1,1-dichlorodialkylsilanes, 1,2-dichlorotetra-alkyldisilanes, and 1,4-bis(chlorodialkylsilyl)benzenes, with Mg electrodes in a single-compartment cell was found to yield the corresponding polysilanes.

Kunai, Atsutaka,Kawakami, Toshihiro,Toyoda, Eiji,Sakurai, Tomohiro,Ishikawa, Mitsuo

, p. 1945 - 1948 (1993)

Electrolytic oxidation of dimethylphenylsilane (1) in the presence of CuCl2 or CuCl afforded chlorodimethylphenylsilane in high yields (>90percent), while similar electrolysis of 1 in the presence of BF4- ions afforded fluorodimethylphenylsilane in 90percent yield. 1,2-Diphenyltetramethyldisilane was obtained from 1 in 48percent yield by the electrolysis with a Pt-Cu electrode system.A "paired" electrolysis of methyldiphenylsilane on the anode and chloromethyldiphenylsilane on the cathode afforded 1,2-dimethyltetraphenyldisilane in 64percent yield.

Copper-Catalyzed Cross-Coupling of Silicon Pronucleophiles with Unactivated Alkyl Electrophiles Coupled with Radical Cyclization

Xue, Weichao,Qu, Zheng-Wang,Grimme, Stefan,Oestreich, Martin

, p. 14222 - 14225 (2016)

A copper-catalyzed C(sp3)-Si cross-coupling of aliphatic C(sp3)-I electrophiles using a Si-B reagent as the silicon pronucleophile is reported. The reaction involves an alkyl radical intermediate that also engages in 5-exo-trig ring closures onto pendant alkenes prior to the terminating C(sp3)-Si bond formation. Several Ueno-Stork-type precursors cyclized with excellent diastereocontrol in good yields. The base-mediated release of the silicon nucleophile and the copper-catalyzed radical process are analyzed by quantum-chemical calculations, leading to a full mechanistic picture.

A Strategy for Accessing Aldehydes via Palladium-Catalyzed C?O/C?N Bond Cleavage in the Presence of Hydrosilanes

He, Zhanyu,Liu, Tingting,Ru, Junxiang,Wang, Yulin,Wang, Zijia,Zeng, Zhuo

supporting information, p. 5794 - 5800 (2020/12/01)

We report the catalytic reduction of both active esters and amides by selective C(acyl)?X (X=O, N) cleavage to access aldehyde functionality via a palladium-catalyzed strategy. Reactions are promoted by hydrosilanes as reducing reagents with good to excellent yields and with excellent chemoselectivity for C(acyl)?N and C(acyl)?O bond cleavage. Carboxylic acid C(acyl)?O bonds are activated by 2-chloro-4,6-dimethoxy-1,3,5-triazine (CDMT) to form triazine ester intermediates, which further react with hydrosilanes to yield aldehydes in one-pot two-step procedures. We demonstrate that C(acyl)?O cleavage/formylation offers higher yields and broader substrate scopes compared with C(acyl)?N cleavage under the same reaction conditions.
