Check Digit Verification of cas no

The CAS Registry Mumber 1223557-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,3,5,5 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1223557-72:
(9*1)+(8*2)+(7*2)+(6*3)+(5*5)+(4*5)+(3*7)+(2*7)+(1*2)=139
139 % 10 = 9
So 1223557-72-9 is a valid CAS Registry Number.

Radical amination with trimethylstannylated benzophenone imine

Lamas, Marie-Celine,Vaillard, Santiago E.,Wibbeling, Birgit,Studer, Armido

supporting information; experimental part, p. 2072 - 2075 (2010/07/07)

Figure presented Intermolecular radical amination reactions of various primary, secondary, and tertiary alkyl radicals by using trimethylstannylated benzophenone imine A as a novel radical acceptor to provide imines of type B are described. These imines are readily reduced with NaBH4 to the corresponding secondary amines C. The novel radical amination can be combined with typical radical cyclization reactions.
