"N-(N-benzyloxycarbonyl-glycyl)-phenylalanine cyanomethyl ester" is a complex organic compound with the molecular formula C21H22N2O5. It is a derivative of phenylalanine, an essential amino acid, and is characterized by the presence of a benzyloxycarbonyl (Cbz) protecting group on the nitrogen atom of the glycine residue. This protecting group is commonly used in peptide synthesis to prevent unwanted side reactions. The cyanomethyl ester group is a reactive moiety that can participate in various chemical reactions, such as nucleophilic substitutions. N-(N-benzyloxycarbonyl-glycyl)-phenylalanine cyanomethyl ester is often used in the synthesis of peptides and other biologically active molecules due to its stability and reactivity. It is a key intermediate in the preparation of more complex peptide structures, where the Cbz group can be selectively removed to reveal the free amine group, allowing for further elongation of the peptide chain.

3338-37-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3338-37-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 8 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3338-37:
(6*3)+(5*3)+(4*3)+(3*8)+(2*3)+(1*7)=82
82 % 10 = 2
So 3338-37-2 is a valid CAS Registry Number.
