5-(4-chlorophenyl)-1-phenyl-3-(thiophen-2-yl)-4,5-dihydro-1H-pyrazole is a complex organic compound with a molecular formula of C18H14ClN2S. It features a pyrazole ring, which is a five-membered aromatic heterocyclic ring containing two nitrogen atoms. The compound has a 4-chlorophenyl group attached to the 5-position of the pyrazole, a phenyl group at the 1-position, and a thiophen-2-yl group at the 3-position. This chemical structure endows the molecule with potential applications in various fields, such as pharmaceuticals and materials science, due to its unique electronic and steric properties. The presence of the chlorine atom on the phenyl ring also suggests that it may be involved in further chemical reactions, such as substitution or addition reactions, making it a versatile building block for the synthesis of more complex molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 5204-22-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5204-22:
(6*5)+(5*2)+(4*0)+(3*4)+(2*2)+(1*2)=58
58 % 10 = 8
So 5204-22-8 is a valid CAS Registry Number.
