Check Digit Verification of cas no

The CAS Registry Mumber 900150-11-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,1,5 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 900150-11:
(8*9)+(7*0)+(6*0)+(5*1)+(4*5)+(3*0)+(2*1)+(1*1)=100
100 % 10 = 0
So 900150-11-0 is a valid CAS Registry Number.

A minimalist approach to C-H activation by copper

Kuebel-Pollak, Anita,Ruettimann, Stephane,Dunn, Nichola,Melich, Xavier,Williams, Alan F.,Bernardinelli, Gerald

, p. 841 - 853 (2006)

The complex [Cu2(1)2]2+ (1=1,3-bis(1-methyl-1H-benzimidazol-2-yl)benzene) undergoes slow oxidation by dioxygen in DMF solution to give the hydroxylated product [Cu 2(2-H)2]2+ (2=2,6-bis(1-methyl-1H-benzimidazol- 2-yl)phenol) characterized by an X-ray crystal-structure analysis. The oxidation occurs much faster when CuII is mixed with 1 in the presence of H2O2, with 80% hydroxylation observed within a few minutes. The mononuclear complex formed with 1-methyl-2-phenyl-1H-benzimidazole (3) shows no hydroxylation under these conditions. It is concluded that the hydroxylation requires the presence of a ligand capable of stabilizing a binuclear species, but no special coordinative activation of the copper is required.
