"Z-Ile-Ala(3Cl)-Leu-OBut" is a synthetic peptide consisting of four amino acids: Isoleucine (Ile), Alanine with a 3-chloro substitution (Ala(3Cl)), Leucine (Leu), and a tert-butyloxycarbonyl (OBut) protecting group. The "Z" prefix indicates that the peptide is protected with a benzyloxycarbonyl group, which is commonly used in peptide synthesis to prevent unwanted side reactions. This specific sequence and protection scheme are likely used in research or pharmaceutical development to study the properties of the peptide or as a building block for larger peptide or protein structures. The 3-chloro substitution on the alanine residue introduces a chlorine atom at the third carbon position, which can significantly alter the chemical and biological properties of the peptide compared to the natural amino acid sequence.

Check Digit Verification of cas no

The CAS Registry Mumber 75816-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,8,1 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75816-48:
(7*7)+(6*5)+(5*8)+(4*1)+(3*6)+(2*4)+(1*8)=157
157 % 10 = 7
So 75816-48-7 is a valid CAS Registry Number.
