The chemical compound "(3aR,4R,10E,12aS)-3a,4,8,9,12,12a-Hexahydro-11-methyl-3-methylene-4,7-metheno-6H-furo[3,2-c]oxacycloundecin-2,6(3H)-dione" is a complex organic molecule with a unique structure. It features a hexahydro core, which means it contains six hydrogen atoms bonded to carbon atoms in a cyclic structure. The compound also includes an 11-methyl group, indicating the presence of a methyl group (CH3) at the 11th position. The 3-methylene and 4,7-metheno bridges suggest the presence of a carbon-carbon double bond (methylene) and a carbon-carbon single bond (metheno) within the molecule. The furan ring, indicated by the "furo" in the name, is a five-membered ring with one oxygen atom, and the "oxacycloundecin" part of the name refers to an oxacyclo ring system with eleven carbon atoms. The compound's structure is further characterized by the presence of a 2,6(3H)-dione group, which implies the presence of two carbonyl groups (C=O) at the 2nd and 6th positions. (3aR,4R,10E,12aS)-3a,4,8,9,12,12a-Hexahydro-11-methyl-3-methylene-4,7-metheno-6H-furo[3,2-c]oxacycloundecin-2,6(3H)-dione is likely to be found in specialized chemical or pharmaceutical contexts due to its intricate structure.

Check Digit Verification of cas no

The CAS Registry Mumber 22391-22-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,3,9 and 1 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 22391-22:
(7*2)+(6*2)+(5*3)+(4*9)+(3*1)+(2*2)+(1*2)=86
86 % 10 = 6
So 22391-22-6 is a valid CAS Registry Number.

NMR and x-ray conformational study of artemisiifolin and three other related germacranolides

Jimeno, Maria L.,Apreda-Rojas, Maria Del Carmen,Cano, Felix H.,Rodriguez, Benjamin

, p. 474 - 483 (2007/10/03)

From an acetone extract of Staehelina dubia, large quantities of the previously known germacranolide artemisiifolin were isolated. The conformations of the 10-membered germacra-1(10)E,4Z-diene ring system of this compound and those of its derivatives 11,13-dihydroartemisiifolin, isabelin and 6α-hydroxy-15-oxogermacra-1(10)E,4Z,11(13)-trien-12,8α-olide were studied by NMR spectroscopic methods. Low-energy conformations were obtained by quantum mechanical calculations. An x-ray diffraction analysis of artemisiifolin established that, in the crystalline state, it possesses a unique conformation that corresponds to the majority one existing in acetone-d6 solution.
