Definition

ChEBI: A C20-gibberellin.

Check Digit Verification of cas no

The CAS Registry Mumber 6980-44-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,8 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6980-44:
(6*6)+(5*9)+(4*8)+(3*0)+(2*4)+(1*4)=125
125 % 10 = 5
So 6980-44-5 is a valid CAS Registry Number.

Metabolism of Steviol and Its Derivatives by Gibberella fujikuroi

Murofushi, Noboru,Shigematsu, Yoshio,Nagura, Shigehiro,Takahashi, Nobutaka

, p. 2305 - 2312 (2007/10/02)

Steviol (ent-13-hydroxykaur-16-en-19-oic acid is metabolized by Gibberella fujikuroi in the presence of inhibitors of gibberellin biosynthesis, such as quaternary ammonium salt-type growth retardants, to afford 7β-hydroxy- and 6β,7β-dihydroxysteviol, gibberellins A1, A18, A19, A53 and 7β,13-dihydroxykaurenolide.Steviol acetate (ent-13-acetoxykaur-16-en-19-oic acid) is also metabolized to the 6β,7β-dihydroxy-derivative and to the 13-acetyl derivatives of gibberellins A17 and A20 and steviol methyl ester (methyl ent-13-hydroxykaur-16-en-19-oate) into the monohydroxy-, dihydroxy- and hydroxyoxo-derivatives.These results indicate a low substrate specificity of the enzymes in the fungus and provide a useful preparative methodology of several important plant gibberellins carrying the 13-hydroxyl group.
