"Nα-Toluol-p-sulfonyl-Nγ-3-tert-butoxycarbonyl-propyl-L-glutaminyl-L-leucin-tert-butylester" is a complex organic compound with a molecular formula that can be represented as C31H48N2O8S. Nα--Nγ-<3-tert-butoxycarbonyl-propyl>-L-glutaminyl-L-leucin-tert-butylester is characterized by its unique structure, which includes a toluene-p-sulfonyl group attached to the α-amino group, a 3-tert-butoxycarbonyl-propyl group attached to the γ-amino group, and a tert-butylester group. It is a derivative of L-glutamine and L-leucine, which are amino acids, and is used in peptide synthesis due to its protecting group strategy. The compound is designed to facilitate the stepwise assembly of peptides by temporarily blocking the reactive amino and carboxyl groups, which are crucial for peptide bond formation. The tert-butoxycarbonyl (Boc) and toluene-p-sulfonyl (Tos) groups serve as protecting groups, which can be removed under specific conditions to expose the reactive sites for further peptide bond formation. Nα--Nγ-<3-tert-butoxycarbonyl-propyl>-L-glutaminyl-L-leucin-tert-butylester is an example of the sophisticated chemistry involved in the synthesis of complex peptides and proteins.
The CAS Registry Mumber 5105-82-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 5 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5105-82: (6*5)+(5*1)+(4*0)+(3*5)+(2*8)+(1*2)=68 68 % 10 = 8 So 5105-82-8 is a valid CAS Registry Number.
