"Z-L-Val-δ-Z-L-Orn-L-Leu-OMe" is a peptide compound consisting of four amino acids: L-Valine (L-Val), δ-Z-L-Ornithine (δ-Z-L-Orn), and L-Leucine (L-Leu), with a methoxy group (OMe) attached to the terminal L-Leucine. The "Z" group represents a benzyloxycarbonyl (Cbz) protecting group, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence and structure of amino acids and protecting groups make it a unique peptide with potential applications in various fields, such as pharmaceuticals, research, and biotechnology.
The CAS Registry Mumber 73870-96-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,8,7 and 0 respectively; the second part has 2 digits, 9 and 6 respectively. Calculate Digit Verification of CAS Registry Number 73870-96: (7*7)+(6*3)+(5*8)+(4*7)+(3*0)+(2*9)+(1*6)=159 159 % 10 = 9 So 73870-96-9 is a valid CAS Registry Number.
