The term "2-thio-" refers to a chemical functional group in which a sulfur atom replaces the oxygen atom in a carbonyl group, specifically in the context of a 2-oxoacid. This substitution results in a 2-thioacid, which can be thought of as a sulfur analog of a 2-oxoacid. The 2-thio- group is characterized by the presence of a carbon-sulfur double bond, which imparts unique chemical properties to the molecule. These compounds are of interest in organic chemistry and biochemistry, as they can participate in various reactions and are found in some natural products and pharmaceuticals. The 2-thio- group can influence the reactivity and stability of the molecule, and its presence can lead to different biological activities compared to the corresponding 2-oxoacid.

Check Digit Verification of cas no

The CAS Registry Mumber 4435-44-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4435-44:
(6*4)+(5*4)+(4*3)+(3*5)+(2*4)+(1*4)=83
83 % 10 = 3
So 4435-44-3 is a valid CAS Registry Number.
