10049-23-7 Usage
General Description
Tellurous(IV) acid, also known as H2TeO3, is a chemical compound that contains the tellurium element in the +4 oxidation state. It is a weak acid with the chemical formula H2TeO3, and is often found in the form of its salts or esters. Tellurous(IV) acid is used in analytical chemistry as a reagent for the determination of certain metals, including antimony and bismuth. It is also employed in the production of tellurium-containing compounds and in the synthesis of tellurium-containing materials. Tellurous(IV) acid has limited commercial use but is important in research and technology for its unique properties and reactivity.
Check Digit Verification of cas no
The CAS Registry Mumber 10049-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,0,4 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10049-23:
(7*1)+(6*0)+(5*0)+(4*4)+(3*9)+(2*2)+(1*3)=57
57 % 10 = 7
So 10049-23-7 is a valid CAS Registry Number.
