"N-(N-benzyloxycarbonyl-L-seryl)-L-glutamic acid dibenzyl ester" is a complex organic compound with the molecular formula C28H31N2O8. It is a derivative of L-glutamic acid, an essential amino acid, and L-serine, a non-essential amino acid. The compound features a benzyloxycarbonyl (Cbz) protecting group on the serine residue, which is commonly used in peptide synthesis to prevent unwanted side reactions. The dibenzyl ester groups are attached to the carboxylic acid moieties of both the glutamic acid and serine residues, further protecting the molecule from unwanted reactions. N-(N-benzyloxycarbonyl-L-seryl)-L-glutamic acid dibenzyl ester is often used in the synthesis of peptides and proteins, where the protecting groups can be selectively removed under specific conditions to facilitate the formation of peptide bonds.

Check Digit Verification of cas no

The CAS Registry Mumber 2543-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,4 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2543-28:
(6*2)+(5*5)+(4*4)+(3*3)+(2*2)+(1*8)=74
74 % 10 = 4
So 2543-28-4 is a valid CAS Registry Number.
