(+/-)-4a-hydroxy-4-oxo-(4aR,8aS)-decahydro-[1c]naphthoic acid-lactone is a complex organic compound with a unique molecular structure. It is characterized by a decahydro-naphthoic acid core, which consists of a decalin (a saturated bicyclic structure) with a naphthalene-like arrangement of carbon atoms. The compound features a hydroxyl group (-OH) at the 4a position and a carbonyl group (C=O) at the 4-oxo position, indicating the presence of a lactone ring. The stereochemistry at the 4a and 8a positions is specified as 4aR and 8aS, which refers to the specific three-dimensional arrangement of the atoms in the molecule. (+/-)-4a-hydroxy-4-oxo-(4ar,8at)-decahydro-[1c]naphthoic acid-lactone is likely to be found in the field of organic chemistry, potentially as an intermediate in the synthesis of more complex molecules or as a component in pharmaceuticals or other chemical industries.

Check Digit Verification of cas no

The CAS Registry Mumber 5656-85-9 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 5656-85:
(6*5)+(5*6)+(4*5)+(3*6)+(2*8)+(1*5)=119
119 % 10 = 9
So 5656-85-9 is a valid CAS Registry Number.
