The chemical compound "(3aR)-3aα,6,7,7aα-Tetrahydro-6-methyl-3-methylene-6α-(4-oxopentyl)-2,5(3H,4H)-benzofurandione" is a complex organic molecule with a unique structure. It features a benzofuran core, which is a type of heterocyclic compound consisting of a benzene ring fused to a furan ring. The compound is characterized by its tetrahydro (partially hydrogenated) nature, a methyl group at the 6-position, and a 3-methylene bridge. Additionally, it has a 4-oxopentyl group attached to the 6α-position, which introduces a ketone functional group into the molecule. This structure gives the compound a range of potential applications in the fields of pharmaceuticals, materials science, and organic chemistry, where its specific properties and reactivity can be exploited.

Check Digit Verification of cas no

The CAS Registry Mumber 89026-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,2 and 6 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 89026-40:
(7*8)+(6*9)+(5*0)+(4*2)+(3*6)+(2*4)+(1*0)=144
144 % 10 = 4
So 89026-40-4 is a valid CAS Registry Number.
