"Z-Val-Lys(Nε)Z-NH-NH2" is a peptide compound consisting of three amino acids: valine (Val), lysine (Lys), and a terminal amino group (NH2). The "Z" groups are protecting groups, which are temporary chemical modifications used in peptide synthesis to prevent unwanted side reactions. The "Nε" indicates that the protecting group is attached to the epsilon nitrogen of the lysine side chain. This specific sequence and protection scheme are crucial for the controlled synthesis of larger peptides or proteins, ensuring that the amino acids are linked in the correct order and that the reactive side chains are protected until the final stages of the synthesis process.

Check Digit Verification of cas no

The CAS Registry Mumber 32303-80-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,3,0 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 32303-80:
(7*3)+(6*2)+(5*3)+(4*0)+(3*3)+(2*8)+(1*0)=73
73 % 10 = 3
So 32303-80-3 is a valid CAS Registry Number.
