5-oxo-1-m-tolyl-4-m-tolylhydrazono-4,5-dihydro-1H-pyrazole-3-carboxylic acid ethyl ester is a complex organic compound with the molecular formula C18H20N2O3. It is characterized by a pyrazole ring, which is a five-membered heterocyclic ring containing one nitrogen atom and one oxygen atom. The compound features two methyl groups (m-tolyl) attached to different positions of the pyrazole ring, and a hydrazone functional group connecting the pyrazole to a carbonyl group. The carboxylic acid group is esterified with an ethyl group, making it an ethyl ester. This chemical is likely to be found in research settings, particularly in the fields of pharmaceuticals or organic chemistry, where it may be used as an intermediate in the synthesis of more complex molecules or as a reagent in chemical reactions.

7104-72-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7104-72-5 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 2 respectively.Calculate Digit Verification of CAS Registry Number 7104-72:
(6*7)+(5*1)+(4*0)+(3*4)+(2*7)+(1*2)=75
75 % 10 = 5
So 7104-72-5 is a valid CAS Registry Number.
