Check Digit Verification of cas no

The CAS Registry Mumber 1421357-44-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,1,3,5 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1421357-44:
(9*1)+(8*4)+(7*2)+(6*1)+(5*3)+(4*5)+(3*7)+(2*4)+(1*4)=129
129 % 10 = 9
So 1421357-44-9 is a valid CAS Registry Number.

Iron-catalyzed allylic arylation of olefins via C(sp3)-H activation under mild conditions

Sekine, Masaki,Ilies, Laurean,Nakamura, Eiichi

, p. 714 - 717 (2013)

An aryl Grignard reagent in the presence of mesityl iodide converts an allylic C-H bond of a cycloalkene or an allylbenzene derivative into a C-C bond in the presence of a catalytic amount of Fe(acac)3 and a diphosphine ligand at 0 C. The stereo- and regioselectivity of the reaction, together with deuterium labeling experiments, suggest that C-H bond activation is the slow step in the catalytic cycle preceding the formation of an allyliron intermediate.
