134532-15-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 134532-15-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,3 and 2 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134532-15:
(8*1)+(7*3)+(6*4)+(5*5)+(4*3)+(3*2)+(2*1)+(1*5)=103
103 % 10 = 3
So 134532-15-3 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 (1991)
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.
