Check Digit Verification of cas no

The CAS Registry Mumber 443919-25-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,9,1 and 9 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 443919-25:
(8*4)+(7*4)+(6*3)+(5*9)+(4*1)+(3*9)+(2*2)+(1*5)=163
163 % 10 = 3
So 443919-25-3 is a valid CAS Registry Number.

Oxidatively induced M-C bond cleavage reactions of Cp*Ir(Me2SO)Me2 and Cp*Rh(Me2SO)Me2 (Cp* = η5-C5Me5)

Fooladi, Erik,Graham, Todd,Turner, Michael L.,Dalhus, Bjorn,Maitlis, Peter M.,Tilset, Mats

, p. 975 - 982 (2002)

Electrochemical and chemical oxidation of Cp*Ir(Me2SO)Me2 (1; Cp* = η5-C5Me5) in Me2SO lead to the formation of methane and traces of ethene (ratio ca. 20:1) as well as Cp*Ir(Me2SO)2Me+. Labeling studies indicate that three of the methane hydrogen atoms arise from the iridium-bonded methyl, while the fourth appears to arise from adventitious water. By contrast, oxidation of the rhodium analog Cp*Rh(Me2SO)Me2 gave only ethane and Cp*Rh(Me2SO)2Me+. Quantitative derivative cyclic voltammetry (DCV) showed that the disappearance of electrode-generated 1·+ follows a rate law that is second order with respect to Ir. The Rh analog 6·+ reacted at rates too great to be measured by DCV under these conditions. Possible mechanisms for these reactions are discussed, and particular attention is paid to the reactivity differences between Rh and Ir. Convenient new syntheses of Cp*Ir(Me2SO)Me2 and Cp*Rh(Me2SO)Me2, as well as X-ray structure determinations of these compounds and of Cp*Ir(Me2SO)2Me+, are reported.
