52083-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 52083-31-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,0,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 52083-31:
(7*5)+(6*2)+(5*0)+(4*8)+(3*3)+(2*3)+(1*1)=95
95 % 10 = 5
So 52083-31-5 is a valid CAS Registry Number.

1,2-Bis(2-aminobenzoyl)hydrazine (1a) reacts with aliphatic acids to yield 2,2'-dialkyl-3,3'-bisquinazolin-4,4'-diones (2).Extension of this reaction to aromatic aldehydes give a mixture of 2,2'-diaryl-tetrahydro-3,3'-bisquinazolin-4,4'-diones (6) and 1,2
