The chemical compound "(3aR,4aS,8aR,9aR)-3-[1-Benzenesulfinyl-meth-(Z)-ylidene]-8a-methyl-5-methylene-decahydro-naphtho[2,3-b]furan-2-one" is a complex, chiral molecule with a unique structure. It features a decahydro-naphtho[2,3-b]furan-2-one core, which is a type of cyclic compound with ten carbon atoms in a decalin-like arrangement, fused to a naphthalene ring. The molecule is characterized by the presence of a 5-methylene group, which is a methylene (CH2) group attached to the naphthalene ring, and an 8a-methyl group, indicating a methyl group at the 8a position. The compound also includes a 3-[1-benzenesulfinyl-meth-(Z)-ylidene] moiety, which is a benzene ring with a sulfinyl group attached to it, and a (Z)-configured ylidene group, suggesting a specific geometric arrangement of the double bond. The chiral centers at the 3a, 4a, 8a, and 9a positions, denoted by the 'R' and 'S' configurations, indicate the specific three-dimensional arrangement of the atoms around these centers. (3aR,4aS,8aR,9aR)-3-[1-Benzenesulfinyl-meth-(Z)-ylidene]-8a-methyl-5-methylene-decahydro-naphtho[2,3-b]furan-2-one is likely to have specific applications in fields such as pharmaceuticals or materials science, where the precise arrangement of atoms can significantly affect its properties and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 76886-53-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,8,8 and 6 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 76886-53:
(7*7)+(6*6)+(5*8)+(4*8)+(3*6)+(2*5)+(1*3)=188
188 % 10 = 8
So 76886-53-8 is a valid CAS Registry Number.

Synthesis of Deuterium-Labeled Sesquiterpene Lactones Isolated from Inula helenium L.

Schaeffer, Marcel,Stampf, Jean-Luc,Benezra, Claude

, p. 6106 - 6113 (2007/10/02)

Reduction of the vinyl sulfoxides 9 and 10 derived from isoalantolactone (1) and alantolactone (2) with NaBD4 yielded deuterium-labeled lactones 11 and 12.Amalgam reduction of sulfides 7 and 8 or sulfoxides 9 and 10 gave labeled products but not the expected deuterated lactones 11 and 12.Satisfactory deuteration of alantolactone 2 could be achieved by CF3COOD hydrolysis of (tributylstannyl)alantolactone (23) obtained in four steps from alantolactone 2.
