Check Digit Verification of cas no

The CAS Registry Mumber 1195791-10-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,5,7,9 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1195791-10:
(9*1)+(8*1)+(7*9)+(6*5)+(5*7)+(4*9)+(3*1)+(2*1)+(1*0)=186
186 % 10 = 6
So 1195791-10-6 is a valid CAS Registry Number.

(Chemical Equation Presented) The synthesis of substituted benzimidazoles, 2-aminobenzimidazoles, 2-aminobenzothiazoles, and benzoxazoles is described via intramolecular cyclization of o-bromoaryl derivatives using copper(II) oxide nanoparticles in DMSO under air. The procedure is experimentally simple, general, efficient, and free from addition of external chelating ligands. It is a heterogeneous process and the copper(II) oxide nanoparticles can be recovered and recycled without loss of activity. 2009 American Chemical Society.
