Valine, 4-(methylthio)-(9CI), also known as 4-(methylthio)-L-valine, is a synthetic amino acid derivative with the chemical formula C7H15NO2S. It is a chiral compound, meaning it has a non-superimposable mirror image, and is commonly found in the L-configuration. Valine, 4-(methylthio)-(9CI) is characterized by the presence of a methylthio group (-SCH3) attached to the 4-position of the valine molecule. Valine, 4-(methylthio)-(9CI), is not an essential amino acid and does not have any known biological functions in humans. It is primarily used in research and development for its unique chemical properties, such as its reactivity and potential applications in the synthesis of pharmaceuticals and other chemical compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 16820-52-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,8,2 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16820-52:
(7*1)+(6*6)+(5*8)+(4*2)+(3*0)+(2*5)+(1*2)=103
103 % 10 = 3
So 16820-52-3 is a valid CAS Registry Number.
