Z-Cys(Bzl)-Phe, also known as N-benzyloxycarbonyl-L-cysteine-L-phenylalanine, is a synthetic peptide consisting of two amino acids: L-cysteine and L-phenylalanine. The L-cysteine is modified with a benzyloxycarbonyl (Bzl) group, which serves as a protecting group for the thiol side chain, preventing unwanted side reactions. Z-Cys(Bzl)-Phe is commonly used in peptide synthesis as a building block, particularly in solid-phase peptide synthesis (SPPS) techniques. The protecting group can be removed under specific conditions, allowing for further reactions or the formation of peptide bonds with other amino acids. Z-Cys(Bzl)-Phe is an essential component in the creation of various bioactive peptides and pharmaceuticals, highlighting its importance in the field of organic chemistry and drug development.

Check Digit Verification of cas no

The CAS Registry Mumber 27317-09-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,3,1 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 27317-09:
(7*2)+(6*7)+(5*3)+(4*1)+(3*7)+(2*0)+(1*9)=105
105 % 10 = 5
So 27317-09-5 is a valid CAS Registry Number.
