"Z(OMe)-Lys(Z)-Lys(Z)-Glu(OBzl)-Val-NHNH-Troc" represents a peptide sequence consisting of six amino acids. The sequence starts with Z(OMe)-Lys, where Z(OMe) is a protecting group for the amino group of lysine, and lysine is an amino acid with a primary amine side chain. The next two amino acids are also lysine, each with a Z protecting group. Following that is Glu(OBzl), which is glutamic acid with an OBzl (benzyl) protecting group on its side chain carboxyl group. The sequence then includes valine, a nonpolar amino acid, and ends with NHNH-Troc, where NHNH represents a terminal amine group and Troc is a protecting group for the amine. This peptide sequence is likely used in peptide synthesis, where the protecting groups are crucial for controlling the reactivity of specific functional groups during the assembly process.
The CAS Registry Mumber 83550-54-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,5 and 0 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 83550-54: (7*8)+(6*3)+(5*5)+(4*5)+(3*0)+(2*5)+(1*4)=133 133 % 10 = 3 So 83550-54-3 is a valid CAS Registry Number.
