Check Digit Verification of cas no

The CAS Registry Mumber 1403758-01-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,7,5 and 8 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1403758-01:
(9*1)+(8*4)+(7*0)+(6*3)+(5*7)+(4*5)+(3*8)+(2*0)+(1*1)=139
139 % 10 = 9
So 1403758-01-9 is a valid CAS Registry Number.

Catalyst-controlled chemoselective arylation of 2-aminobenzimidazoles

Ueda, Satoshi,Buchwald, Stephen L.

supporting information, p. 10364 - 10367 (2012/11/13)

What N would you like? The chemoselective and complementary Pd- and Cu-catalyzed N-arylation of 2-aminobenzimidazoles is described. Selective N-arylation of the amino group was achieved with a Pd-catalyzed method, while selective N-arylation of azole nitrogen was achieved with a Cu-catalyzed procedure (see scheme). Copyright
