"Nα-(α-L-Glutamyl)-Nε-tosyl-L-lysin-methylester" is a complex peptide compound that consists of a lysine residue with a methyl ester group attached to its amino group (Nα) and a tosyl group attached to its ε-amino group. The compound is further characterized by the presence of an α-L-glutamyl moiety, which is linked to the lysine through its α-carboxylate group. This structure is significant in the field of peptide chemistry, as it represents a type of protected amino acid that can be used in the synthesis of larger peptides and proteins. The tosyl group serves as a protecting group for the ε-amino group, preventing unwanted side reactions during peptide synthesis, while the methyl ester group can be used to control the reactivity of the Nα amino group. N^α-(α-L-Glutamyl)-N^ε-tosyl-L-lysin-methylester is a valuable tool in the synthesis of peptides with specific functionalities and can be found in research settings where controlled peptide assembly is required.

Check Digit Verification of cas no

The CAS Registry Mumber 5891-58-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,9 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5891-58:
(6*5)+(5*8)+(4*9)+(3*1)+(2*5)+(1*8)=127
127 % 10 = 7
So 5891-58-7 is a valid CAS Registry Number.
