"Z-Glu(OBu^t)-Val-Glu(OBu^t)-Gly-OEt" is a peptide compound consisting of four amino acids: glutamic acid (Glu), valine (Val), and glycine (Gly). The peptide is synthesized with a Z-group (benzyloxycarbonyl) protecting group on the N-terminus, which is commonly used in peptide synthesis to prevent unwanted side reactions. The glutamic acid residues are modified with tert-butyl (OBu^t) protecting groups on their side chains, which protect the carboxylic acid groups during synthesis. The final product is an ethyl ester (OEt), indicating that the C-terminus is esterified, which can be used to improve solubility or for controlled release applications. This specific sequence and modification are likely designed for a particular biological activity or stability profile in a research or pharmaceutical context.

Check Digit Verification of cas no

The CAS Registry Mumber 74221-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,2 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74221-45:
(7*7)+(6*4)+(5*2)+(4*2)+(3*1)+(2*4)+(1*5)=107
107 % 10 = 7
So 74221-45-7 is a valid CAS Registry Number.
