"Z-Glut>-OBut" is a complex peptide derivative, where "Z" stands for the carbobenzoxy group, a protecting group used in peptide synthesis to prevent unwanted side reactions. "Glu" represents the amino acid glutamic acid. The "OBut" groups are tert-butyloxy protecting groups attached to the hydroxyl groups of the glutamic acid residues, which prevent them from participating in unwanted reactions during peptide synthesis. Z-Glut>-OBut is a dipeptide, consisting of two glutamic acid units, with one glutamic acid residue being N-terminally protected by a Z group and both residues having their side chain hydroxyl groups protected by OBut groups. This structure is important in the field of peptide chemistry, as it allows for the controlled synthesis of larger peptides and proteins with specific sequences and properties.

Check Digit Verification of cas no

The CAS Registry Mumber 25456-77-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,4,5 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 25456-77:
(7*2)+(6*5)+(5*4)+(4*5)+(3*6)+(2*7)+(1*7)=123
123 % 10 = 3
So 25456-77-3 is a valid CAS Registry Number.
