Check Digit Verification of cas no

The CAS Registry Mumber 1042159-64-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,2,1,5 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1042159-64:
(9*1)+(8*0)+(7*4)+(6*2)+(5*1)+(4*5)+(3*9)+(2*6)+(1*4)=117
117 % 10 = 7
So 1042159-64-7 is a valid CAS Registry Number.

Orthogonal Pd- and Cu-based catalyst systems for C- and N-arylation of oxindoles

Altman, Ryan A.,Hyde, Alan M.,Huang, Xiaohua,Buchwald, Stephen L.

supporting information; scheme or table, p. 9613 - 9620 (2009/02/02)

In the cross-coupling reactions of unprotected oxindoles with aryl halides, Pd- and Cu-based catalyst systems displayed orthogonal chemoselectivity. A Pd-dialkylbiarylphosphine-based catalyst system chemoselectively arylated oxindole at the 3 position, while arylation occurred exclusively at the nitrogen using a Cu-diamine-based catalyst system. Computational examination of the relevant L1Pd(Ar)(oxindolate) and diamine-Cu(oxindolate) species was performed to gain mechanistic insight into the controlling features of the observed chemoselectivity.
