The chemical compound "(+/-)-1ξ-hydroxy-4a-methyl-(4ar,8ac)-4a,5,8,8a-tetrahydro-1H-naphthalen-2-one" is a complex organic molecule with a unique structure. It belongs to the class of naphthalenones, which are derivatives of naphthalene, a bicyclic aromatic hydrocarbon. This specific compound features a hydroxyl group (-OH) at the 1ξ position, a methyl group (-CH3) at the 4a position, and a tetrahydro ring structure, indicating four hydrogen atoms added to the naphthalene ring, which reduces the molecule's aromaticity. The compound's stereochemistry is defined by the "4ar,8ac" notation, suggesting specific spatial arrangements of the atoms at these positions. The "1H" indicates that one of the rings in the molecule is partially hydrogenated, and the "2-one" ending signifies the presence of a ketone group (C=O) at the 2 position. (+/-)-1ξ-hydroxy-4a-methyl-(4ar,8ac)-4a,5,8,8a-tetrahydro-1H-naphthalen-2-one is a racemic mixture, as indicated by the "(+/-)" prefix, meaning it contains equal amounts of both the R and S enantiomers.
The CAS Registry Mumber 5453-54-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,5 and 3 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5453-54: (6*5)+(5*4)+(4*5)+(3*3)+(2*5)+(1*4)=93 93 % 10 = 3 So 5453-54-3 is a valid CAS Registry Number.
