The CAS Registry Mumber 131989-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,8 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 131989-75:
(8*1)+(7*3)+(6*1)+(5*9)+(4*8)+(3*9)+(2*7)+(1*5)=158
158 % 10 = 8

HYDROXY-(METHYLBUTENYNYL)-BENZOIC ACID AND DERIVATIVES FROM CURVULARIA FALLAX

Abraham, Wolf-Rainer,Arfmann, Hans-Adolf

, p. 2641 - 2644 (1990)

4-Hydroxy-3-(3'-methyl-2'-butenyl)-benzoic acid, 4-hydroxy-3-(3'-methyl-3'-buten-1'-inyl)-benzoic acid, 2-isopropenylbenzofuran-5-carboxylic acid, anofinic acid and its 3,4-trans-dihydroxy derivative were isolated from the fungus Curvularia fallax.Biotransformation with p-amino-benzoic acid led to the corresponding 3-prenylbenzoic acid while 2,4-dihydroxybenzoic acid was alkylated in 5-position.Other related substrates were not prenylated by the microorganism.The biosynthesis of these compounds in C. fallax and Streptomyces niveus is compared.
