N,N'-bis-[1-(2-fluoro-5-nitro-phenyl)-2-nitro-ethyl]-benzidine is a complex organic compound with the chemical formula C24H18FN5O6. It is a derivative of benzidine, a well-known aromatic amine, with two nitro-ethyl groups attached to the nitrogen atoms. Each of these groups contains a 2-fluoro-5-nitro-phenyl moiety, which introduces fluorine and nitro functional groups into the molecule. N,N'-bis-[1-(2-fluoro-5-nitro-phenyl)-2-nitro-ethyl]-benzidine is characterized by its yellow color and is often used as a pigment or dye in various industrial applications due to its color properties. However, it is important to note that benzidine and its derivatives are known to be carcinogenic, and therefore, their use is strictly regulated in many countries to minimize health risks.
The CAS Registry Mumber 612-32-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 2 respectively; the second part has 2 digits, 3 and 2 respectively. Calculate Digit Verification of CAS Registry Number 612-32: (5*6)+(4*1)+(3*2)+(2*3)+(1*2)=48 48 % 10 = 8 So 612-32-8 is a valid CAS Registry Number.
