The chemical compound "(3aR)-3aβ,4,5,5a,6,7,8,9bα-Octahydro-4β-hydroxy-5aα,9-dimethyl-3-methylenenaphtho[1,2-b]furan-2(3H)-one" is a complex organic molecule with a unique structure. It belongs to the class of naphthofuran derivatives, which are heterocyclic compounds containing both a naphthalene ring and a furan ring. This specific compound features an octahydro system, indicating the presence of eight hydrogen atoms bonded to carbon atoms in a cyclic structure. The 4β-hydroxy group suggests a hydroxyl group (-OH) is attached to the β-carbon of the naphthalene ring. Additionally, the compound has two methyl groups (-CH3) at the 5aα and 9 positions, and a methylene group (-CH2-) at the 3 position, which is part of a double bond, indicating the presence of a methylene bridge. The compound's stereochemistry is defined by the (3aR) configuration, which specifies the arrangement of atoms in three-dimensional space. This molecule is characterized by its specific geometric arrangement and functional groups, which contribute to its unique chemical properties and potential applications in various fields, such as pharmaceuticals or materials science.

33530-72-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 33530-72-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,5,3 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 33530-72:
(7*3)+(6*3)+(5*5)+(4*3)+(3*0)+(2*7)+(1*2)=92
92 % 10 = 2
So 33530-72-2 is a valid CAS Registry Number.
