Z-Ser-Leu-Pro-NHNHBoc is a peptide compound consisting of four amino acids: serine (Ser), leucine (Leu), and proline (Pro), with an N-hydroxybenzotriazole (NHNHBoc) protecting group. This sequence is a part of a larger protein or polypeptide chain, and the protecting group is used to prevent unwanted side reactions during peptide synthesis. The Z group, or benzyloxycarbonyl group, is a temporary protecting group for the amino group of serine, which is crucial for maintaining the peptide's structure during synthesis. Once the peptide is fully synthesized, the Z group can be removed to reveal the free amino group, allowing for further reactions or interactions with other molecules.
The CAS Registry Mumber 78578-33-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,7 and 8 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 78578-33: (7*7)+(6*8)+(5*5)+(4*7)+(3*8)+(2*3)+(1*3)=183 183 % 10 = 3 So 78578-33-3 is a valid CAS Registry Number.
