10242-40-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10242-40-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,4 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 10242-40:
(7*1)+(6*0)+(5*2)+(4*4)+(3*2)+(2*4)+(1*0)=47
47 % 10 = 7
So 10242-40-7 is a valid CAS Registry Number.

Synthesis and structures of heterobimetallic Ir2M (M=Pd, Pt) sulfido clusters and their catalytic activity for regioselective addition of alcohols to internal 1-aryl-1-alkynes

The heterobimetallic trinuclear suffido clusters [(Cp*Ir)2(μ3-S)2MCl2] (M = Pd (3), Pt (4); Cp* = η5-C5Me5) were synthesized from the dinuclear hydrogensulfido complex [Cp*IrCl(μ

Regioselective addition of alcohols to internal 1-aryl-1-alkynes catalyzed by a triangular heterobimetallic Ir2Pd sulfido cluster

Masui, Dai,Ishii, Youichi,Hidai, Masanobu

, p. 717 - 718 (2007/10/03)

The triangular heterobimetallic sulfido cluster [(Cp*Ir)2(μ3-S)2PdCl2] prepared from [PdCl2(cod)] and [Cp*IrCl(μ-SH)2IrCp*Cl] was found to catalyze the addition of alcohols to alkynes to give the corresponding ketals. In particular, internal 1-aryl-1-alkynes were transformed into the corresponding 2,2-dialkoxy-1-arylalkanes with high regioselectivity. The analogous Ir2PtS2 cluster proved to be much less selective.
