"Z(OMe)-Leu-Gly-Cys(Tmb)-Asn-Ser-Phe-Arg(Mts)-Tyr-OBzl" is a peptide sequence consisting of a series of amino acids. It starts with Z(OMe), which is a protecting group for the N-terminus of the peptide. The sequence then includes Leucine (Leu), Glycine (Gly), Cysteine with a Tmb (Thiomethylbutyryl) group, Asparagine (Asn), Serine (Ser), Phenylalanine (Phe), Arginine with an Mts (4-Methyltrityl) group, Tyrosine (Tyr), and ends with an OBzl (Benzyl) protecting group on the C-terminus. This specific arrangement of amino acids and modifications is likely designed for a particular biological or chemical purpose, such as studying protein interactions or as a component in a drug design. The presence of protecting groups suggests that this peptide is intended for use in chemical synthesis or as a precursor in a larger molecular assembly.
The CAS Registry Mumber 99236-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,2,3 and 6 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 99236-53: (7*9)+(6*9)+(5*2)+(4*3)+(3*6)+(2*5)+(1*3)=170 170 % 10 = 0 So 99236-53-0 is a valid CAS Registry Number.
