"Z-Cys(Bzl)-Pro-Lys(Tos)-Gly-NH2" is a peptide compound consisting of five amino acids: Cysteine (Cys), Proline (Pro), Lysine (Lys), Glycine (Gly), and an additional terminal amino group (NH2). The "Z" group is a protecting group for the cysteine residue, while the "Bzl" (benzyl) and "Tos" (tosyl) groups are protecting groups for the cysteine and lysine residues, respectively. This specific sequence and protection pattern are used in peptide synthesis to control the reactivity of certain amino acids and prevent unwanted side reactions. The compound is of interest in the field of organic chemistry and biochemistry, particularly in the synthesis of larger peptides and proteins, where the protecting groups are crucial for controlling the reaction conditions and ensuring the correct sequence of amino acids is formed.
The CAS Registry Mumber 34714-97-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,1 and 4 respectively; the second part has 2 digits, 9 and 7 respectively. Calculate Digit Verification of CAS Registry Number 34714-97: (7*3)+(6*4)+(5*7)+(4*1)+(3*4)+(2*9)+(1*7)=121 121 % 10 = 1 So 34714-97-1 is a valid CAS Registry Number.
