"Nα-<3,5-Dimethoxy-benzyloxycarbonyl>-ε-benzyloxycarbonyl-L-lysin" is a complex organic compound that serves as a protecting group in peptide synthesis. It is a derivative of the amino acid L-lysine, where the α-amino group is protected by a 3,5-dimethoxy-benzyloxycarbonyl (Dmb) group, and the ε-amino group is protected by a benzyloxycarbonyl (Z) group. This specific combination of protecting groups is used to prevent unwanted side reactions during the synthesis of peptides, ensuring that the L-lysine residue remains unreacted until the desired point in the synthesis process. The Dmb group is known for its acid stability, which is beneficial for protecting the α-amino group during acidic conditions often encountered in peptide synthesis, while the Z group is labile under mild acidic conditions, allowing for selective deprotection. Nα-<3,5-Dimethoxy-benzyloxycarbonyl>-ε-benzyloxycarbonyl-L-lysin is crucial in the field of medicinal chemistry and biotechnology for the controlled assembly of peptide sequences.
The CAS Registry Mumber 6806-12-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,0 and 6 respectively; the second part has 2 digits, 1 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6806-12: (6*6)+(5*8)+(4*0)+(3*6)+(2*1)+(1*2)=98 98 % 10 = 8 So 6806-12-8 is a valid CAS Registry Number.
