"3a,4,5,6a-tetraphenyl-3a,6a-dihydrocyclopenta[c]pyrazol-6(3H)-one" is a complex organic compound characterized by its unique molecular structure. It features a cyclopenta[c]pyrazol-6(3H)-one core, which is a type of pyrazole ring fused to a cyclopentane ring. The molecule is adorned with four phenyl groups attached to the 3a, 4, 5, and 6a positions, which contribute to its stability and potential applications in various chemical and pharmaceutical contexts. 3a,4,5,6a-tetraphenyl-3a,6a-dihydrocyclopenta[c]pyrazol-6(3H)-one is a derivative of the parent cyclopenta[c]pyrazole structure, with the added complexity of the dihydro and tetraphenyl modifications. The specific arrangement of these phenyl groups and the dihydro functionality can influence the compound's physical and chemical properties, making it a subject of interest for researchers in organic synthesis and potentially in the development of new materials or drugs.
The CAS Registry Mumber 989-16-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,8 and 9 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 989-16: (5*9)+(4*8)+(3*9)+(2*1)+(1*6)=112 112 % 10 = 2 So 989-16-2 is a valid CAS Registry Number.
