1-(2,4-dinitro-phenyl)-3-ethyl-4,5-dihydro-1H-pyrazole is a complex organic compound with the molecular formula C11H12N4O5. It is characterized by a pyrazole ring, which is a five-membered heterocyclic ring containing three nitrogen atoms. The compound features a 2,4-dinitrophenyl group attached to the pyrazole ring, which contributes to its chemical properties. The presence of two nitro groups (-NO2) at the 2nd and 4th positions of the phenyl ring enhances its reactivity and potential applications. Additionally, an ethyl group (-CH2CH3) is attached to the 3rd position of the pyrazole ring, further influencing its chemical behavior. 1-(2,4-dinitro-phenyl)-3-ethyl-4,5-dihydro-1H-pyrazole may have applications in various fields, such as pharmaceuticals, agrochemicals, or as intermediates in the synthesis of other complex molecules, due to its unique structure and reactivity.

Check Digit Verification of cas no
The CAS Registry Mumber 5920-23-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5920-23:
(6*5)+(5*9)+(4*2)+(3*0)+(2*2)+(1*3)=90
90 % 10 = 0
So 5920-23-0 is a valid CAS Registry Number.
