Z-D-Ser(Boc-Val)-Ala-OTce is a peptide compound consisting of four amino acids: D-serine, Boc-protected valine, alanine, and a terminal alcohol group (OTce). The "Z" prefix indicates the presence of a carbobenzoxy (Cbz) protecting group on the N-terminus, which is commonly used in peptide synthesis to prevent unwanted side reactions. The "D" prefix before serine signifies that it is the D-configuration of the amino acid, which is the non-natural enantiomer. The Boc group (tert-butyloxycarbonyl) is a protecting group for the side chain of valine, which is crucial for maintaining the integrity of the peptide during synthesis. Z-D-Ser(Boc-Val)-Ala-OTce is used in the synthesis of larger peptides and proteins, with the protecting groups being removed at specific stages to allow for further reactions.
The CAS Registry Mumber 63478-50-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,4,7 and 8 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 63478-50: (7*6)+(6*3)+(5*4)+(4*7)+(3*8)+(2*5)+(1*0)=142 142 % 10 = 2 So 63478-50-2 is a valid CAS Registry Number.
