100556-43-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 100556-43-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,5,5 and 6 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100556-43:
(8*1)+(7*0)+(6*0)+(5*5)+(4*5)+(3*6)+(2*4)+(1*3)=82
82 % 10 = 2
So 100556-43-2 is a valid CAS Registry Number.

Construction of Chiral Tri- and Tetra-Arylmethanes Bearing Quaternary Carbon Centers: Copper-Catalyzed Enantioselective Propargylation of Indoles with Propargylic Esters

Tsuchida, Kouhei,Senda, Yasushi,Nakajima, Kazunari,Nishibayashi, Yoshiaki

, p. 9728 - 9732 (2016)

Copper-catalyzed enantioselective propargylation of indoles with propargylic esters and sequential Huisgen cycloaddition with azides lead to the construction of chiral triarylmethanes, bearing a quaternary carbon center, with high to excellent enantioselectivities. The result described herein can be used in the enantioselective preparation of a tetraarylmethane.

The coordination chemistry and reactivity of amino-dithiaphospholanes with rhodium, iridium, and ruthenium

Costin, Stephen,Sedinkin, Sergey L.,Bauer, Eike B.

scheme or table, p. 922 - 925 (2009/05/27)

Novel amino-dithiaphospholane complexes of ruthenium, iridium, and rhodium were synthesized, and their properties were studied. Reaction of the new amino-dithiaphospholane (RS)2PNR2′ (R = binaphthyl, R′ = CH2Ph,

2-Propynylamines from 1,1-Dibromo-1-alkenes

Frey, Herbert,Kaupp, Gerd

, p. 931 - 934 (2007/10/02)

Easily accessible 1,1-dibromo-1-alkenes react with primary or secondary amines in a complex series of reactions to give directly N-substituted or N,N-disubstituted (1-Alkyl-1-aryl-2-propynyl)amines 5 in useful yields.This simple method avoids the isolation of intermediates (bromoacetylenes or bromoallenes) and makes a series of 2-propynylamines with an acetylenic hydrogen available.
