3,3-diphenyl-tetrahydro-cyclopenta[b]pyran-2,4-dione is a complex organic compound with a molecular formula of C19H18O3. It features a cyclopenta[b]pyran core, which is a five-membered ring fused with a pyran (a six-membered oxygen-containing ring). The compound is characterized by two phenyl groups attached to the third carbon of the cyclopenta[b]pyran ring, which contribute to its stability and aromatic properties. The 2,4-dione functional group indicates the presence of two carbonyl groups at the second and fourth positions, which are crucial for the compound's reactivity and potential applications in various chemical processes. This molecule is of interest in organic chemistry due to its unique structure and the possibility of further functionalization, making it a potential candidate for pharmaceutical or materials science research.
The CAS Registry Mumber 1459-35-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 9 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1459-35: (6*1)+(5*4)+(4*5)+(3*9)+(2*3)+(1*5)=84 84 % 10 = 4 So 1459-35-4 is a valid CAS Registry Number.
