Calculate Digit Verification of CAS Registry Number 904734-81:
(8*9)+(7*0)+(6*4)+(5*7)+(4*3)+(3*4)+(2*8)+(1*1)=172
172 % 10 = 2
So 904734-81-2 is a valid CAS Registry Number.

A phosphonamidate containing aromatic N-terminal amino group as inhibitor of leucine aminopeptidase-design, synthesis and stability

Mucha,Kunert,Grembecka,Pawelczak,Kafarski

, p. 768 - 772 (2007/10/03)

Fully deprotected phosphonamidate dipeptides, predicted as effective inhibitors of cytosolic leucine aminopeptidase, showed unexpected instability in water solution at pH below 12. Their hydrolysis rate was strictly correlated with basicity of the N-termi
