The chemical compound in question is a complex, polycyclic structure with a unique arrangement of atoms and bonds. It is a derivative of decahydrofuro[3''',2''':5'',6'']benzo[1'',2'':2',3']cyclopropa[1',2':4,5]cyclopenta[1,2-d]isoxazole-2,6-dione, which features a decahydro (10-carbon) ring system fused with a benzene ring and a cyclopropa ring. The compound is characterized by its 3aS, 5a, and 5b trimethyl groups, indicating three methyl groups attached to the 3a, 5a, and 5b carbon atoms, respectively. Additionally, it has a diphenyl group at the 8,9 positions, which means two phenyl rings are attached to the 8th and 9th carbon atoms. The compound also has a 2,6-dione functional group, indicating the presence of two carbonyl groups at the 2nd and 6th positions. The stereochemistry is specified with various prefixes such as 3ar, 5ac, 5bt, 6ac, 9ac, and 9bc, which describe the spatial arrangement of the atoms in the molecule. This complex structure likely has specific applications in fields such as pharmaceuticals or materials science, where the precise arrangement of atoms can significantly influence the compound's properties and reactivity.
The CAS Registry Mumber 17658-99-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,6,5 and 8 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 17658-99: (7*1)+(6*7)+(5*6)+(4*5)+(3*8)+(2*9)+(1*9)=150 150 % 10 = 0 So 17658-99-0 is a valid CAS Registry Number.
