"Z(OMe)-Cys(Bzl)-Arg(Tos)-NHNH2" is a peptide compound consisting of four amino acids: Z(OMe)-Cysteine, Cysteine with a benzyl group (Cys(Bzl)), Arginine with a tosyl group (Arg(Tos)), and a terminal hydrazine group (NHNH2). The "Z(OMe)" group is a protecting group for the cysteine amino acid, which is crucial for preventing unwanted side reactions during peptide synthesis. The benzyl group in Cys(Bzl) serves a similar protective role. The tosyl group in Arg(Tos) is another protecting group that can be removed under specific conditions to reveal the free amino group. The terminal hydrazine group is a functional group that can participate in various chemical reactions, such as forming hydrazones or coupling with aldehydes and ketones. This specific sequence and modification of amino acids are likely used in the synthesis of a particular peptide or protein with specific biological or chemical properties, where the protecting groups allow for controlled synthesis and the terminal hydrazine group provides a reactive handle for further modification or conjugation.

Check Digit Verification of cas no

The CAS Registry Mumber 52885-31-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,8,8 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 52885-31:
(7*5)+(6*2)+(5*8)+(4*8)+(3*5)+(2*3)+(1*1)=141
141 % 10 = 1
So 52885-31-1 is a valid CAS Registry Number.
