Check Digit Verification of cas no
The CAS Registry Mumber 93-46-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93-46:
(4*9)+(3*3)+(2*4)+(1*6)=59
59 % 10 = 9
So 93-46-9 is a valid CAS Registry Number.

METHOD FOR PRODUCING PHENYLENE DIAMINE DERIVATIVE
-
Paragraph 0107-0116; 0119, (2021/05/28)
PROBLEM TO BE SOLVED: To provide a method for producing a phenylene diamine derivative that produces a phenylene diamine derivative having excellent economical efficiency and safety, and polymerization inhibitory performance. SOLUTION: A method for producing a phenylene diamine derivative is to produce a reaction mixture containing a phenylene diamine derivative by causing a reaction to occur between o-phenylenediamine, m-phenylenediamine, or p-phenylenediamine and a phenol. In the reaction, solid iodine as a catalyst is changed into a solution state through a solvent, and the solution is dropped as a catalyst onto a reaction system.
