Norleucine, also known as 2-amino-4-methylvaleric acid, is a non-proteinogenic amino acid that is structurally similar to leucine but with a methyl group replacing the alpha-hydrogen atom. It is a synthetic compound that is not found in nature and is used in various applications, including pharmaceuticals, as a building block for peptide synthesis, and in the production of certain drugs. Norleucine is also used in scientific research to study protein structure and function, as well as in the development of new therapeutic agents. Its unique properties make it a valuable tool in the field of biochemistry and drug discovery.

Check Digit Verification of cas no

The CAS Registry Mumber 5157-09-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,5 and 7 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 5157-09:
(6*5)+(5*1)+(4*5)+(3*7)+(2*0)+(1*9)=85
85 % 10 = 5
So 5157-09-5 is a valid CAS Registry Number.
