Definition
ChEBI: A sesquiterpene lactone that is 3,3a,4,4a,7a,8,9,9a-octahydroazuleno[6,5-b]furan-2,5-dione substituted by methyl groups at positions 4a and 8 and a methylidene group at position 3. Isolated from the aerial parts of Inula hupehensis
Check Digit Verification of cas no
The CAS Registry Mumber 5945-42-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,4 and 5 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5945-42:
(6*5)+(5*9)+(4*4)+(3*5)+(2*4)+(1*2)=116
116 % 10 = 6
So 5945-42-6 is a valid CAS Registry Number.

Allylsilane-Based Annulations. Direct Stereoselective Syntheses of (+/-)-Graveolide and (+/-)-Aromaticin
Majetich, George,Song, Jee-Seop,Leigh, Alistair J.,Condon, Stephen M.
, p. 1030 - 1037 (2007/10/02)
An allylsilane-based annulation was used to construct a functionalized perhydroazulene.The C(1), C(5), and C(10) stereocenters, characteristic of the helenanolides, were established using a reductive alkylation strategy.Stereoselective syntheses of the pseudoguaianolides graveolide and aromaticin were achieved.
