(3aR,4aR,8aS,9R,9aR)-2,7-Diphenyl-3a,4a,5,8a,9,9a-hexahydro-3,4,6,8-tetraoxa-1-aza-cyclopenta[b]naphthalen-9-ol is a complex organic compound characterized by its unique molecular structure. It features a cyclopenta[b]naphthalene core, which is a type of fused ring system consisting of a cyclopentane ring and a naphthalene ring. The compound is further defined by its hexahydro and tetraoxa substitutions, indicating the presence of six hydrogen atoms and four oxygen atoms in the molecule. The phenyl groups at positions 2 and 7 contribute to its aromatic character. The stereochemistry is specified by the R and S configurations at various carbon centers, which are crucial for its three-dimensional structure and potential biological activity. (3aR,4aR,8aS,9R,9aR)-2,7-Diphenyl-3a,4a,5,8a,9,9a-hexahydro-3,4,6,8-tetraoxa-1-aza-cyclopenta[b]naphthalen-9-ol is of interest in the field of organic chemistry, potentially for its pharmaceutical or chemical properties, although specific applications or uses are not detailed in the provided information.
The CAS Registry Mumber 81347-98-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,4 and 7 respectively; the second part has 2 digits, 9 and 8 respectively. Calculate Digit Verification of CAS Registry Number 81347-98: (7*8)+(6*1)+(5*3)+(4*4)+(3*7)+(2*9)+(1*8)=140 140 % 10 = 0 So 81347-98-0 is a valid CAS Registry Number.
