Calculate Digit Verification of CAS Registry Number 80825-28:
(7*8)+(6*0)+(5*8)+(4*2)+(3*5)+(2*2)+(1*8)=131
131 % 10 = 1
So 80825-28-1 is a valid CAS Registry Number.

Synthesis of 2-amino-5(6)-(4-aminophenyl)benzimidazole derivatives: II. Reaction of 2-nitro-4-thiocyanatoaniline with 4-nitrochlorobenzene

Pilyugin,Sapozhnikov,Shitov

, p. 979 - 984 (2003)

The reaction of 2-nitro-4-thiocyanatoaniline with 4-nitrochlorobenzene in aqueous alkaline medium in the presence of phase-transfer catalyst at 95-100°C was studied with a view to obtain 4-amino-3,4′- dinitrodiphenyl sulfide. Optimal conditions for the synthesis and isolation of the product were found.
