3533-47-9 Usage
General Description
The chemical compound "(3aS,7R)-3',3aβ,4,4',5,6,8,8aβ-Octahydro-8β-hydroxy-6α,8-dimethyl-3-methylenespiro[7H-cyclohepta[b]furan-7,2'(5'H)-furan]-2,5'(3H)-dione," is a complex spirocyclic molecule with a fused furan ring system. It has a cyclohepta[b]furan core and contains a dione functional group. The compound also features multiple stereocenters and a hydroxy group at the 8β position. Its structural complexity and stereochemistry make it an interesting target for chemical synthesis and potentially for biological studies.
Check Digit Verification of cas no
The CAS Registry Mumber 3533-47-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,3 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3533-47:
(6*3)+(5*5)+(4*3)+(3*3)+(2*4)+(1*7)=79
79 % 10 = 9
So 3533-47-9 is a valid CAS Registry Number.

Naturally occurring acetylated pseudoguaianolides and psilostachyin including their analogues were synthesized. The structure of semi-synthetic psilostachyin was also confirmed by X-ray crystallography. The anti-inflammatory potential of all the derivatives has been evaluated through in vitro expression of TNF-α, IL-1β and IL-6 in murine neutrophils.
