"Z(NO2)-Leu-Met-NH2" is a peptide compound consisting of three amino acids: Leucine (Leu), Methionine (Met), and a terminal amino group (NH2). The "Z(NO2)" group is a protecting group, specifically a nitrobenzyl group, which is used in peptide synthesis to protect the amino group of the first amino acid in the sequence. This protection is crucial during the synthesis process to prevent unwanted side reactions. The nitrobenzyl group can be removed under specific conditions once the peptide chain is complete, allowing for further reactions or analysis. This particular sequence is often used in the study of peptide synthesis and protein chemistry, as it represents a simple model for understanding the behavior of amino acids in peptide bonds and the effects of protecting groups on peptide stability and reactivity.

Check Digit Verification of cas no

The CAS Registry Mumber 3190-67-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3190-67:
(6*3)+(5*1)+(4*9)+(3*0)+(2*6)+(1*7)=78
78 % 10 = 8
So 3190-67-8 is a valid CAS Registry Number.
