Check Digit Verification of cas no

The CAS Registry Mumber 1248587-68-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,8,5,8 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1248587-68:
(9*1)+(8*2)+(7*4)+(6*8)+(5*5)+(4*8)+(3*7)+(2*6)+(1*8)=199
199 % 10 = 9
So 1248587-68-9 is a valid CAS Registry Number.

Palladium-catalyzed amination of unprotected halo-7-azaindoles

Henderson, Jaclyn L.,McDermott, Sarah M.,Buchwald, Stephen L.

supporting information; experimental part, p. 4438 - 4441 (2010/12/20)

Simple and efficient procedures for the Pd-catalyzed cross-coupling of primary and secondary amines with halo-7-azaindoles(pyrrolo[2,3-b]pyridine) are presented. Previously, no general method was available to ensure the highly selective reaction of the heteroaryl halide in the presence of the unprotected azaindole N-H. Using palladium precatalysts recently reported by our group, such reactions are easily accomplished under mild conditions that can be applied to cross-coupling reactions with a wide array of aliphatic and aromatic amines.
