Uses
9(S)-HOTrE is a monohydroxy polyunsaturated fatty acid produced by the action of 5-lipoxygenase on α-linolenic acid. 9(S)-HOTrE is predominantly localized in cellular ester lipids of Glechoma hederacea leaves and is partially released during artificial dehydration. The biological role of 9(S)-HOTrE in G. hederacea leaves is still undetermined, but it may play a role in natural senescence. 9(S)-HOTrE is an inhibitor of spore germination and germ tube elongation of rice blast fungus with ED50 values of 45 and 30 ppm, respectively.[Cayman Chemical]
Definition
ChEBI: A 9-HOTrE consisting of (10E,12Z,15Z)-octadecatrienoic acid in which the 9-hydroxy group has S-configuration.
Check Digit Verification of cas no
The CAS Registry Mumber 89886-42-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,8,8 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89886-42:
(7*8)+(6*9)+(5*8)+(4*8)+(3*6)+(2*4)+(1*2)=210
210 % 10 = 0
So 89886-42-0 is a valid CAS Registry Number.

Efficient syntheses of (10E,12Z,15Z)-9-oxo- and (9Z,11E,15E)-13-oxo-octadecatrienoic acids; two stress metabolites of wounded plants

Configurationally pure 9-oxo-10E,12Z,15Z- and 13-oxo-9Z,11E,15E-octadecatrienoic acid are available from linolenic acid via regioselective functionalisation using lipoxygenases from soybean or tomato at specific pH conditions. Reduction of the resulting hydroperoxides followed by oxidation of the resulting allylic alcohols with Bobbitt's reagent yields the configurationally pure but labile ketotrienoic acids 4 and 5 without concomitant isomerisation.
