3-bromo-1-(2,4-dinitro-phenyl)-4,5-dihydro-1H-pyrazole is a complex organic compound with the molecular formula C8H7BrN4O4. It features a pyrazole ring, which is a five-membered aromatic ring containing three nitrogen atoms, fused to a benzene ring. The compound is characterized by the presence of a bromine atom at the 3-position, and two nitro groups (-NO2) at the 2 and 4 positions of the phenyl ring. The 4,5-dihydro part of the name indicates that the pyrazole ring is partially saturated, with two hydrogen atoms added to the ring structure. 3-bromo-1-(2,4-dinitro-phenyl)-4,5-dihydro-1H-pyrazole may have potential applications in the fields of pharmaceuticals, agrochemicals, or as a synthetic intermediate due to its unique structure and functional groups.

Check Digit Verification of cas no

The CAS Registry Mumber 5920-74-1 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, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5920-74:
(6*5)+(5*9)+(4*2)+(3*0)+(2*7)+(1*4)=101
101 % 10 = 1
So 5920-74-1 is a valid CAS Registry Number.
