155-54-4 Usage

Uses

DL-Dihydoorotic Acid is used in the production of orotic acid and methyl dihydroorotate (D449975). DL-Dihydoorotic Acid is one of many components used for enhancing the biosynthesis of hyaluronic acid.

Definition

ChEBI: A pyrimidinemonocarboxylic acid that results from the base-catalysed cyclisation of Nalpha-carbethoxyasparagine.

Check Digit Verification of cas no

The CAS Registry Mumber 155-54-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,5 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 155-54:
(5*1)+(4*5)+(3*5)+(2*5)+(1*4)=54
54 % 10 = 4
So 155-54-4 is a valid CAS Registry Number.
