"Z-Glu(Cys(SO2NH2)-Gly-OEt)-OEt" is a complex chemical compound, primarily used in peptide synthesis. It consists of a glutamic acid (Glu) residue, which is modified with a benzyloxycarbonyl (Z) protecting group, a cysteine (Cys) residue with a sulfonamide group (SO2NH2), a glycine (Gly) residue, and two ethyl ester (OEt) groups. Z-Glu(Cys(SO₂NH₂)-Gly-OEt)-OEt is crucial in the synthesis of specific peptides, as the protecting groups help prevent unwanted side reactions during the assembly process. The Z group protects the carboxylic acid group of glutamic acid, while the OEt groups protect the amino group of the peptide. The sulfonamide group in the cysteine residue can be used for further functionalization or conjugation to other molecules. Overall, "Z-Glu(Cys(SO2NH2)-Gly-OEt)-OEt" is a key building block in the creation of more complex peptide structures with specific properties and functions.

Check Digit Verification of cas no

The CAS Registry Mumber 33642-60-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,6,4 and 2 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 33642-60:
(7*3)+(6*3)+(5*6)+(4*4)+(3*2)+(2*6)+(1*0)=103
103 % 10 = 3
So 33642-60-3 is a valid CAS Registry Number.
