73995-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73995-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,9,9 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 73995-50:
(7*7)+(6*3)+(5*9)+(4*9)+(3*5)+(2*5)+(1*0)=173
173 % 10 = 3
So 73995-50-3 is a valid CAS Registry Number.

Synthesis of peptides potentially involved in the biosynthesis of clavulanic acid
Negro,Garzon,Martin,El Marini,Roumestant,Lazaro
, p. 359 - 369 (2007/10/02)
Two peptides were synthetised by coupling 3-hydroxy propionic acid with L-ornithine and 3-hydroxy-DL-ornithine, to be tested later in order to establish whether they are links in the biosynthesis of clavulanic acid.
