5-oxo-1-o-tolyl-4-o-tolylhydrazono-4,5-dihydro-1H-pyrazole-3-carboxylic acid ethyl ester is a complex organic compound with the molecular formula C18H20N4O3. It is characterized by a pyrazole ring, which is a five-membered aromatic ring containing three nitrogen atoms. The compound features two tolyl groups (methylphenyl groups) attached to the pyrazole ring, with one being an o-tolyl (2-methylphenyl) and the other a p-tolyl (4-methylphenyl). The 5-oxo group indicates the presence of a carbonyl (C=O) group at the 5-position of the pyrazole ring. Additionally, the compound has a carboxylic acid group at the 3-position, which is esterified with an ethyl group, making it an ethyl ester. This chemical structure suggests potential applications in pharmaceuticals or as a synthetic intermediate in organic chemistry, given its unique arrangement of functional groups and aromatic systems.

7104-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7104-71-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,0 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 7104-71:
(6*7)+(5*1)+(4*0)+(3*4)+(2*7)+(1*1)=74
74 % 10 = 4
So 7104-71-4 is a valid CAS Registry Number.
