2,4-Dioxo-2,3,4,5,6,7-hexahydro-spiro-(cyclopenta[b]pyran-3,1'-cyclopentan) is a complex organic compound characterized by its unique molecular structure. It features a spiro ring system, which consists of two fused rings sharing a common atom. In this case, the rings are a cyclopenta[b]pyran and a cyclopentan, with the latter being hexahydro-derivative, meaning it contains six hydrogen atoms attached to the carbon atoms. The compound also has two carbonyl groups (indicated by the "2,4-dioxo") at the 2nd and 4th positions, which contribute to its reactivity and functional properties. This chemical is of interest in organic chemistry and may have potential applications in the synthesis of pharmaceuticals or other specialty chemicals due to its intricate structure and functional groups.
The CAS Registry Mumber 3242-55-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,4 and 2 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3242-55: (6*3)+(5*2)+(4*4)+(3*2)+(2*5)+(1*5)=65 65 % 10 = 5 So 3242-55-5 is a valid CAS Registry Number.
