The CAS Registry Mumber 1333149-05-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,3,1,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1333149-05:
(9*1)+(8*3)+(7*3)+(6*3)+(5*1)+(4*4)+(3*9)+(2*0)+(1*5)=125
125 % 10 = 5
So 1333149-05-5 is a valid CAS Registry Number.

Copper(II) acetate/oxygen-mediated nucleophilic addition and intramolecular C-H activation/C-N or C-C bond formation: One-pot synthesis of benzimidazoles or quinazolines

He, Hua-Feng,Wang, Zhi-Jing,Bao, Weiliang

, p. 2905 - 2912 (2010)

Diarylcarbodiimides or benzylphenylcarbodiimides are converted to 1,2-disubstituted benzimidazoles or 1,2-disustituted quinazolines via addition/intramolecular C-H bond activation/C-N or C-C bond forming reaction using copper(II) acetate/oxygen [Cu(OAc)2/O2] as the oxidant at 100°C in one-pot cascade procedure.
