"Nα-Tosyl-Nγ-tosylglycyl-L-α,γ-diamino-buttersaeure" is a complex chemical compound, often used in peptide synthesis and protein chemistry. It is a derivative of L-α,γ-diamino-buttersaeure, a naturally occurring amino acid. The compound is characterized by the presence of two tosyl groups, one attached to the Nα (alpha-amino) group and the other to the Nγ (gamma-amino) group. Tosyl, or toluenesulfonyl, is a protecting group used to prevent unwanted side reactions during peptide synthesis. Nα-Tosyl-Nγ-tosylglycyl-L-α,γ-diamino-buttersaeure is significant in the field of biochemistry and molecular biology, as it can be used to create specific peptide sequences with controlled reactivity, which is crucial for the study of protein structure and function.
The CAS Registry Mumber 4127-85-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,2 and 7 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4127-85: (6*4)+(5*1)+(4*2)+(3*7)+(2*8)+(1*5)=79 79 % 10 = 9 So 4127-85-9 is a valid CAS Registry Number.
