Z-D-Ser(Boc-MeVal)-Ala-OTce is a peptide compound consisting of four amino acids: D-serine, Boc-protected methylvaline, alanine, and a t-butyloxycarbonyl (Boc) protecting group. The compound is named based on its sequence and the protecting groups present. Z represents the benzyloxycarbonyl (Cbz) protecting group, which is commonly used to protect the N-terminus of the peptide. D-Ser refers to D-serine, an amino acid with a chiral center at the second carbon. Boc-MeVal denotes Boc-protected methylvaline, where the Boc group is used to protect the side chain of the amino acid. Ala is short for alanine, a simple amino acid without a side chain. OTce represents the t-butyloxycarbonyl protecting group attached to the C-terminus of the peptide. Z-D-Ser(Boc-MeVal)-Ala-OTce is used in peptide synthesis, where protecting groups are essential to prevent unwanted side reactions and ensure the correct sequence of amino acids in the final product.
The CAS Registry Mumber 68098-67-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,0,9 and 8 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 68098-67: (7*6)+(6*8)+(5*0)+(4*9)+(3*8)+(2*6)+(1*7)=169 169 % 10 = 9 So 68098-67-9 is a valid CAS Registry Number.
