83890-46-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83890-46-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,9 and 0 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 83890-46:
(7*8)+(6*3)+(5*8)+(4*9)+(3*0)+(2*4)+(1*6)=164
164 % 10 = 4
So 83890-46-4 is a valid CAS Registry Number.

Process for synthesis of N,N-disubstituted hydrazone

-

, (2008/06/13)

A process for synthesizing an N,N-disubstituted hydrazone comprises carrying out nitrozation by adding an aqueous solution of sodium nitrite to a solution having one part by weight of an N,N-disubstituted amine dissolved in 3 to 30 parts by weight of an organic acid, then reducing the nitrozated product to an N,N-disubstituted hydrazine by adding a reducing agent to the mixture containing the nitrozated product, and thereafter adding to the mixture containing the N,N-disubstituted hydrazine a carbonyl compound of the formula: STR1 wherein A represents an aromatic hydrocarbon group or an aromatic heterocyclic group which may have a substituent, B represents a hydrogen atom, an alkyl group, an aryl group or an aromatic heterocyclic group, which may have a substituent, thereby performing condensation of the N,N-disubstituted hydrazine with the carbonyl compound.
