Check Digit Verification of cas no
The CAS Registry Mumber 1520-46-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,2 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1520-46:
(6*1)+(5*5)+(4*2)+(3*0)+(2*4)+(1*6)=53
53 % 10 = 3
So 1520-46-3 is a valid CAS Registry Number.

Iron-Catalyzed Remote Arylation of Aliphatic C-H Bond via 1,5-Hydrogen Shift
Zhou, Bingwei,Sato, Hiroki,Ilies, Laurean,Nakamura, Eiichi
, p. 8 - 11 (2018/01/17)
Catalytic amounts of an iron(III) salt and a N-heterocyclic carbene ligand catalyze the arylation of 2-iodoalkylarenes with diphenylzinc selectively at the C-H bond of the alkyl side chain. Several lines of evidence suggest that the iron catalyst reacts with the aryl iodide moiety of the substrate to generate an aryliron intermediate that behaves in a radical manner and cleaves the aliphatic C-H bond through 1,5-hydrogen transfer; the resulting alkyliron intermediate undergoes reductive elimination to give the arylated product.
