ZAsp(OBzl)cHex, also known as Z-Asp(OBzl)-cHex, is a synthetic peptide building block that plays a crucial role in the synthesis of cyclic peptides. It consists of a cyclic hexapeptide (cHex) with a D-aspartic acid (Asp) residue, which is protected by an orthobenzoic acid (OBzl) group. This protection is essential to prevent unwanted side reactions during peptide synthesis. The "Z" prefix indicates the presence of a benzyloxycarbonyl (Z) protecting group on the N-terminus, which is commonly used to prevent peptide chain elongation until the desired sequence is complete. ZAsp(OBzl)cHex is a valuable component in the field of peptide chemistry, particularly for the construction of complex cyclic peptide structures with specific biological activities.

Check Digit Verification of cas no

The CAS Registry Mumber 30221-02-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,2,2 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 30221-02:
(7*3)+(6*0)+(5*2)+(4*2)+(3*1)+(2*0)+(1*2)=44
44 % 10 = 4
So 30221-02-4 is a valid CAS Registry Number.

Determination of Enantiomers of Amino Acids by Reversed Phase High Performance Liquid Chromatography

Gilon, C.,Leshem, R.,Grushka, Eli

, p. 1206 - 1209 (1980)

The chromatographic resolution of enantiomeric amino acids is accomplished on reverse phase columns using aqueous mobile phases containing the chiral reagent L-aspartylcyclohexylamide-Cu(II).This reagent has the additional advantage that t
