126-49-8 Usage

Definition

ChEBI: An oxo dicarboxylic acid that consists of 4-hydroxycyclohexa-2,5-diene-1-carboxylic acid substituted by a 2-carboxy-2-oxoethyl group at position 1.

Check Digit Verification of cas no

The CAS Registry Mumber 126-49-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126-49:
(5*1)+(4*2)+(3*6)+(2*4)+(1*9)=48
48 % 10 = 8
So 126-49-8 is a valid CAS Registry Number.

Prephenic dehydrogenase, a soluble enzyme from E. coli, catalyzes an aromatization reaction which converts prephenic acid (PPA) to p-hydroxyphenylpyruvic acid (HPP) with DPN as the oxidant. The absence of this reaction in tyrosine auxotrophs indicates that it is an obligatory step in tyrosine bi...detailed
