Check Digit Verification of cas no

The CAS Registry Mumber 1001915-83-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,1,9,1 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1001915-83:
(9*1)+(8*0)+(7*0)+(6*1)+(5*9)+(4*1)+(3*5)+(2*8)+(1*3)=98
98 % 10 = 8
So 1001915-83-8 is a valid CAS Registry Number.

A direct, regioselective palladium-catalyzed synthesis of N-substituted benzimidazoles and imidazopyridines

Alonso, Jorge,Halland, Nis,Nazare, Marc,R'Kyek, Omar,Urmann, Matthias,Lindenschmidt, Andreas

supporting information; experimental part, p. 234 - 237 (2011/03/20)

Unsymmetric, N-substituted benzimidazoles and imidazopyridines can be prepared directly from 2-halonitroarenes and amides through Pd(TFA) 2/(R)-BINAP-catalyzed cross-coupling and subsequent reductive aminocyclization. This sequence can be conducted by a one-pot procedure. The method is versatile and allows the straightforward, regioselective preparation of these important nitrogen heterocycles.

A REGIOSELECTIVE COPPER CATALYZED SYNTHESIS OF BENZIMIDAZOLES AND AZABENZIMIDAZOLES

-

Page/Page column 30-31, (2009/03/07)

The present invention relates to a process for the regioselective synthesis of compounds of the formula (I), wherein R0; R1; R2; R3; R4; R5; A1; A2; A3; A4; Q and J have the meanings indicated in the claims. The present invention provides a direct copper catalyzed regioselective process to a wide variety of unsymmetrical, multifunctional N/-substituted benzimidazoles or azabenzimidazoles of formula I starting from 2-halo-nitroarenes and N/-substituted amides. The process is useful for the production of pharmaceuticals, diagnostic agents, liquid crystals, polymers, herbicides, fungicidals, nematicidals, parasiticides, insecticides, acaricides and arthropodicides.
