N-<3,5-Dimethoxy-benzyloxycarbonyl>-L-serin, also known as N-(3,5-dimethoxybenzyloxycarbonyl)-L-serine, is a chemical compound with the molecular formula C13H19NO7. It is a derivative of L-serine, an amino acid, where the hydroxyl group of the serine molecule is protected by a 3,5-dimethoxybenzyloxycarbonyl (DMBC) group. This protection is crucial in organic synthesis, particularly in peptide synthesis, to prevent unwanted side reactions and ensure the selective formation of the desired peptide bonds. The DMBC group can be removed under mild acidic conditions, making it a valuable protecting group for the hydroxyl group in serine. N-<3,5-Dimethoxy-benzyloxycarbonyl>-L-serin is widely used in the pharmaceutical industry for the synthesis of complex peptides and other biologically active molecules.
The CAS Registry Mumber 6436-78-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,3 and 6 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6436-78: (6*6)+(5*4)+(4*3)+(3*6)+(2*7)+(1*8)=108 108 % 10 = 8 So 6436-78-8 is a valid CAS Registry Number.
