α-Deuterio-toluol-α-sulfonsaeure-methylester, also known as α-deuterium toluene-α-sulfonic acid methyl ester, is a chemical compound derived from toluene. It is characterized by the presence of a deuterium atom (a hydrogen isotope with one neutron and one proton) in the α-position of the toluene molecule, which is the carbon atom directly attached to the methyl group. α-Deuterio-toluol-α-sulfonsaeure-methylester also features a sulfonic acid group at the α-position, which is then esterified with methanol to form the methyl ester. The resulting molecule has the chemical formula C9H12D2O3S, and it is a potential intermediate in the synthesis of various organic compounds, particularly those requiring deuterated aromatic rings. Due to its unique properties, it may be used in the preparation of isotopically labeled compounds for research purposes or in specialized industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 5877-97-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5877-97:
(6*5)+(5*8)+(4*7)+(3*7)+(2*9)+(1*7)=144
144 % 10 = 4
So 5877-97-4 is a valid CAS Registry Number.
