"N(α)-Benzyloxycarbonyl-N(ε)-tosyl-L-lysyl-L-threoninmethylester" is a complex peptide derivative that consists of three amino acids: L-lysine, L-threonine, and a methyl ester group. The L-lysine residue is protected at the α-amino group with a benzyloxycarbonyl (Cbz) group, which is a common protecting group in peptide synthesis to prevent unwanted side reactions. The ε-amino group of L-lysine is further modified with a tosyl (Tos) group, which serves as a protecting group and can be selectively removed under certain conditions. The L-threonine is linked to the L-lysine through a peptide bond, and the molecule is capped with a methyl ester group at the carboxylic acid end, which can be used to facilitate solubility or as a handle for further chemical modifications. N(α)-Benzyloxycarbonyl-N(ε)-tosyl-L-lysyl-L-threoninmethylester is significant in the field of peptide chemistry, where such protected amino acid derivatives are crucial for the synthesis of larger peptides and proteins with controlled reactivity and selectivity.
The CAS Registry Mumber 7010-92-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,1 and 0 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 7010-92: (6*7)+(5*0)+(4*1)+(3*0)+(2*9)+(1*2)=66 66 % 10 = 6 So 7010-92-6 is a valid CAS Registry Number.
