Check Digit Verification of cas no

The CAS Registry Mumber 1217438-38-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,4,3 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1217438-38:
(9*1)+(8*2)+(7*1)+(6*7)+(5*4)+(4*3)+(3*8)+(2*3)+(1*8)=144
144 % 10 = 4
So 1217438-38-4 is a valid CAS Registry Number.

Palladium-catalyzed amination of aromatic C-H bonds with oxime esters

Tan, Yichen,Hartwig, John F.

supporting information; experimental part, p. 3676 - 3677 (2010/05/15)

"Chemical equation presented" We report a conceptually new approach to the direct amination of aromatic C-H bonds. In this process, an oxime ester function reacts with an aromatic C-H bond under redox-neutral conditions to form, in the case studied, an indole product. These reactions occur with relatively low catalyst loading (1 mol %) by a mechanism that appears to involve an unusual initial oxidative addition of an N-O bond to a Pd(0) species. The Pd(II) complex from oxidative addition of the N-X bond has been isolated for the first time, and evidence for the intermediacy of such oxidative addition products in the catalytic reaction has been gained.
