Calculate Digit Verification of CAS Registry Number 90687-25:
(7*9)+(6*0)+(5*6)+(4*8)+(3*7)+(2*2)+(1*5)=155
155 % 10 = 5
So 90687-25-5 is a valid CAS Registry Number.

BRIEF SYNTHESES OF (+/-)-METHYL SHIKIMATE, (+/-)-METHYL EPISHIKIMATE AND STRUCTURAL VARIANTS

Campbell, Malcolm M.,Kaye, Aston D.,Sainsbury, Malcolm,Yavarzadeh, Roya

, p. 2461 - 2470 (2007/10/02)

Two brief syntheses of (+/-)-methyl shikimate are described in a strategy which offers potentially flexible access to a range of analogues.New intramolecular rearrangement reactions of epoxides derived from methyl 7-oxabicyclohept-3-ene 6-carboxylate and methyl bicyclohept-3-ene 6 carboxylate are described.

COMPLEMENTARY SHORT SYNTHESES OF (+/-)-METHYL SHIKIMATE

Campbell, Malcolm M.,Kaye, Aston D.,Sainsbury, Malcolm,Yavarzadeh, Roya

, p. 1629 - 1630 (2007/10/02)

Two syntheses of (+/-)-methyl shikimate from the adduct of furan and methyl acrylate are described.One requires the regioselective hydroxylation of (+/-)-5β,6β-dihydroxy-O,O-isopropylidene-2-methoxycarbonylcyclohexa-1,3-diene and the other cis-dihydroxyla
