Check Digit Verification of cas no

The CAS Registry Mumber 1239886-78-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,8,8 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1239886-78:
(9*1)+(8*2)+(7*3)+(6*9)+(5*8)+(4*8)+(3*6)+(2*7)+(1*8)=212
212 % 10 = 2
So 1239886-78-2 is a valid CAS Registry Number.

Copper-catalyzed synthesis of phenanthridine derivatives under an oxygen atmosphere starting from biaryl-2-carbonitriles and grignard reagents

Zhang, Line,Ang, Gim Yean,Chiba, Shunsuke

supporting information; experimental part, p. 3682 - 3685 (2010/10/20)

A copper-catalyzed synthesis of phenanthridine derivatives was developed starting from biaryl-2-carbonitriles and Grignard reagents. The present transformation is carried out by a sequence of nucleophilic addition of Grignard reagents to biaryl-2-carbonitriles to form N-H imines and their Cu-catalyzed C-N bond formation on the aromatic C-H bond, where molecular oxygen is a prerequisite to achieve the catalytic process.
