3,5-Pyrazolidinedione, 1,2-diphenyl-4-(1H-pyrrol-2-ylmethylene)-, also known as 1,2-diphenyl-4-(1H-pyrrol-2-ylmethylene)-3,5-pyrazolidinedione, is a complex organic compound with the molecular formula C18H14N2O2. It is characterized by a pyrazolidinedione core, which is a five-membered ring containing two nitrogen atoms, and is further substituted with two phenyl groups at the 1 and 2 positions. The 4-position is adorned with a pyrrol-2-ylmethylene group, which adds a pyrrole ring and a methylene bridge to the structure. 3,5-Pyrazolidinedione, 1,2-diphenyl-4-(1H-pyrrol-2-ylmethylene)- is of interest in organic chemistry and may have potential applications in the synthesis of pharmaceuticals or other specialty chemicals due to its unique structure and reactivity.
The CAS Registry Mumber 2652-82-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 2 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 2652-82: (6*2)+(5*6)+(4*5)+(3*2)+(2*8)+(1*2)=86 86 % 10 = 6 So 2652-82-6 is a valid CAS Registry Number.
