General Description
3-Amino-4-Pyridazinecarboxylic Acid is a chemical compound belonging to the class of organic compounds called aminopyridazines and derivatives. These are organic compounds containing an amino group attached to a pyridazine ring. It is primarily used in scientific research and it's not naturally occurring. Its structure is characterized by a pyridazine ring, which is a six-membered aromatic ring with two nitrogen atoms, and a carboxylic acid group. The presence of the carboxylic acid group makes it slightly acidic, and the presence of the amino group can make it a potential precursor for other chemicals.
Check Digit Verification of cas no
The CAS Registry Mumber 21141-03-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,4 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21141-03:
(7*2)+(6*1)+(5*1)+(4*4)+(3*1)+(2*0)+(1*3)=47
47 % 10 = 7
So 21141-03-7 is a valid CAS Registry Number.
