Naphtho[1,2-b]furan-2(3H)-one, decahydro-3,5a,9-trimethyl-, (3S,3aS,5aR,9S,9aS,9bS)- is a complex organic compound with a unique molecular structure. It is characterized by a naphtho-furan core, which is a fusion of a naphthalene and a furan ring. The compound is decahydro, meaning it contains ten hydrogen atoms in its structure, and has three methyl groups attached at positions 3, 5a, and 9. The stereochemistry of the compound is specified by the (3S,3aS,5aR,9S,9aS,9bS) notation, indicating the spatial arrangement of these atoms. Naphtho[1,2-b]furan-2(3H)-one,decahydro-3,- 5a,9-trimethyl-,(3S,3aS,5aR,9S,9aS,9bS)- is likely to be found in specialized chemical research or as an intermediate in the synthesis of more complex organic molecules, given its specific structure and stereochemistry.

2221-83-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2221-83-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,2 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2221-83:
(6*2)+(5*2)+(4*2)+(3*1)+(2*8)+(1*3)=52
52 % 10 = 2
So 2221-83-2 is a valid CAS Registry Number.

Oxidation Studies on 5αH,4,6,11βH-Eudesman-6,13-diol

Jorapur, V. S.,Shaligram, A. M.

, p. 709 - 710 (2007/10/02)

Oxidation of 5αH,4,6,11βH-eudesman-6,13-diol (6) with various Cr(VI) reagents has been studied.With pyridinium chlorochromate, the stable lactol (2) has been isolated for the first time along with the keto alcohol (9) and santanolide 'a' (4).All other oxidising reagents used invariably furnish 4 and 9 as the reaction product.
