33345-17-4 Usage
General Description
N,N'-Diphenylbenzamidine (DPB) is a chemical compound composed primarily of Carbon, Hydrogen, and Nitrogen atoms. It is an aromatic amine featuring a benzene ring with a secondary amine group (NH), which contributes to its strong oxidizing properties. These properties make it very effective at initiating polymerization, a process crucial in creating valuable materials like plastic, paint, adhesives, and more. DPB is typically synthesized via the condensation reaction between benzanilide and aniline. However, it should be noted that its usage requires proper handling and safety measures due to its toxicity.
Check Digit Verification of cas no
The CAS Registry Mumber 33345-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,4 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33345-17:
(7*3)+(6*3)+(5*3)+(4*4)+(3*5)+(2*1)+(1*7)=94
94 % 10 = 4
So 33345-17-4 is a valid CAS Registry Number.
