Z-Ala-Gly-Cys(MBzl)-Lys(Z)-OMe is a peptide compound consisting of five amino acids: Z-protected alanine (Z-Ala), glycine (Gly), benzyl-protected cysteine (Cys(MBzl)), Z-protected lysine (Lys(Z)), and methoxy-protected serine (OMe). This specific sequence of amino acids is linked together by peptide bonds, forming a linear chain. The Z-group (benzyloxycarbonyl) and MBzl (benzyl) are protecting groups that shield the amino and carboxylic acid groups, respectively, during peptide synthesis to prevent unwanted side reactions. The OMe group is a methoxy protecting group attached to the hydroxyl group of serine. This peptide is of interest in chemical and biological research, particularly in the study of protein structure, function, and synthesis, as well as in the development of new drugs and therapeutics.
The CAS Registry Mumber 56936-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,9,3 and 6 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 56936-40: (7*5)+(6*6)+(5*9)+(4*3)+(3*6)+(2*4)+(1*0)=154 154 % 10 = 4 So 56936-40-4 is a valid CAS Registry Number.
