Check Digit Verification of cas no
The CAS Registry Mumber 31432-60-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,3 and 2 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 31432-60:
(7*3)+(6*1)+(5*4)+(4*3)+(3*2)+(2*6)+(1*0)=77
77 % 10 = 7
So 31432-60-7 is a valid CAS Registry Number.

Method for producing 4-nitrosodiphenylamine
-
, (2008/06/13)
A method for producing 4-nitrosodiphenylamine, consisting in diphenylamine nitrozation with nitrites of alkali metals or ammonium nitrite in the presence of an acid and an organic solvent nonmiscible with water; said nitrozation being carried out under stirring with a speed determined by Reynolds number not below, 8-10×103 or in the presence of polymers of methacrylic acid esters in an amount of 0.01-0.02% of the reaction mixture weight under stirring with a speed determined by Reynolds number equal to 4-5×103 ; this is followed by rearrangement of the resultant N-nitrosodiphenylamine with anhydrous hydrogen chloride in an inert gas atmosphere in the presence of an alkyl 4-aminodiphenylamine in an amount of 0.5-1% of the N-nitrosodiphenylamine weight, with subsequent neutralization of the formed 4-nitrosodiphenylamine hydrochloride and isolation of the desired product. The method described above makes it possible to increase the product yield at the nitrozation stage by a factor of 5-6 and to raise the yield of the desired product up to 99% in terms of the converted N-nitrosodiphenylamine. 4-Nitrosodiphenylamine produced serves as an intermediate in the synthesis of antioxidants for rubbers and plastics, in the synthesis of dyestuffs, and is also used as a component in a number of antioxidant compositions.
