L-Methionine, N-[N-[(1,1-dimethylethoxy)carbonyl]-L-seryl]-, methyl ester is a complex organic compound with the chemical formula C14H26N2O5S. It is a derivative of the essential amino acid L-methionine, featuring a serine residue attached to the methionine through a carbonyl group. The serine is protected by a 1,1-dimethylethoxycarbonyl (DME) group, which is a common protecting group in peptide synthesis to prevent unwanted side reactions. The methyl ester group indicates that the carboxylic acid group of the serine is esterified with a methyl group. L-Methionine, N-[N-[(1,1-dimethylethoxy)carbonyl]-L-seryl]-, methyl ester is significant in the field of peptide chemistry, where it can be used as a building block for the synthesis of larger peptides and proteins, with the DME group being removed at a later stage to reveal the free serine carboxylic acid group, allowing for further peptide bond formation.

3262-71-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3262-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,6 and 2 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3262-71:
(6*3)+(5*2)+(4*6)+(3*2)+(2*7)+(1*1)=73
73 % 10 = 3
So 3262-71-3 is a valid CAS Registry Number.
