Check Digit Verification of cas no

The CAS Registry Mumber 1442981-61-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,2,9,8 and 1 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1442981-61:
(9*1)+(8*4)+(7*4)+(6*2)+(5*9)+(4*8)+(3*1)+(2*6)+(1*1)=174
174 % 10 = 4
So 1442981-61-4 is a valid CAS Registry Number.

Fe-catalysed Kumada-type alkyl-alkyl cross-coupling. Evidence for the intermediacy of Fe(i) complexes

Guisan-Ceinos, Manuel,Tato, Francisco,Bunuel, Elena,Calle, Paloma,Cardenas, Diego J.

, p. 1098 - 1104 (2013)

A novel Fe-NHC catalytic system allows the alkyl-alkyl cross-coupling reaction of alkyl halides and alkylmagnesium reagents has been developed. To our knowledge, this is the first Fe-catalysed Kumada-type coupling for the formation of C(sp3)-C(sp3) bonds in the presence of functional groups. The process takes place under mild conditions, avoiding the formation of β-elimination products. Mechanistic studies suggest the intermediacy of Fe(i) complexes, formed by reduction with the Grignard reagent, as the active species.
