(+/-)-4t,4a-dihydroxy-(4ar,8at)-decahydro-[1c]naphthoic acid-4a lactone is a complex organic compound with a unique molecular structure. It is a chiral molecule, indicated by the (+/-) notation, which means it has both R and S configurations. The compound consists of a decahydro-naphthoic acid core, which is a type of hydrocarbon with a decalin (bicyclo[4.4.0]decane) structure. The molecule features two hydroxyl groups at the 4t and 4a positions, and a lactone ring at the 4a position, which is formed by the intramolecular esterification of the carboxylic acid group with a hydroxyl group. This lactone ring contributes to the compound's stability and reactivity. The compound's stereochemistry is defined by the 4ar and 8at descriptors, which indicate the relative positions of the substituents around the decalin ring. (+/-)-4t,4a-dihydroxy-(4ar,8at)-decahydro-[1c]naphthoic acid-4a lactone is of interest in organic chemistry and may have potential applications in pharmaceuticals or materials science due to its specific structural features.
The CAS Registry Mumber 5656-84-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,5 and 6 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5656-84: (6*5)+(5*6)+(4*5)+(3*6)+(2*8)+(1*4)=118 118 % 10 = 8 So 5656-84-8 is a valid CAS Registry Number.
