Check Digit Verification of cas no

The CAS Registry Mumber 162174-56-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,1,7 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 162174-56:
(8*1)+(7*6)+(6*2)+(5*1)+(4*7)+(3*4)+(2*5)+(1*6)=123
123 % 10 = 3
So 162174-56-3 is a valid CAS Registry Number.

A general and efficient iron-catalyzed benzylation of 1,3-dicarbonyl compounds

Kischel, Jette,Mertins, Kristin,Michalik, Dirk,Zapf, Alexander,Beller, Matthias

, p. 865 - 870 (2008/03/18)

Various CH-acidic 1,3-dicarbonyl compounds and methyl 3-acetamidobut-2- enoate react with benzylic alcohols to give the corresponding 2-benzylated products in good to excellent yield. Typically, reactions proceed under mild conditions (50-80°C; air) in the presence of catalytic amounts of inexpensive iron chloride hexahydrate. The benzylation of 4-hydroxycoumarin gives the pharmaceutically interesting 4-hydroxy-3-(1-phenylethyl)-2H-chromen-2- ones. As an example the anticoagulant Phenprocoumon is prepared in one step from commercially available substrates in 94 % yield.
