It is a derivative of decahydronaphthalene, which is a saturated analog of naphthalene. The compound features a naphthalene core with three methyl groups attached to the 5, 5, and 8a positions, and a but-3-enyl group at the 1 position. The 2-oxo group indicates the presence of a carbonyl group at the 2 position. This specific stereochemistry, with the 1S, 4aS, and 8aS configurations, refers to the arrangement of atoms in three-dimensional space. The compound is likely to be found in the context of organic chemistry research or as an intermediate in the synthesis of more complex molecules.
The CAS Registry Mumber 71876-57-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,8,7 and 6 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 71876-57: (7*7)+(6*1)+(5*8)+(4*7)+(3*6)+(2*5)+(1*7)=158 158 % 10 = 8 So 71876-57-8 is a valid CAS Registry Number.
