Sulfuric acid monoethyl ester, also known as ethyl sulfate or ethyl hydrogen sulfate, is an organic compound with the chemical formula C2H6O4S. It is formed by the reaction of ethanol with sulfuric acid, resulting in an ester that is widely used as a solvent, a reagent in organic synthesis, and a precursor in the production of various chemicals. Barium compounds, on the other hand, are a group of inorganic substances that contain the element barium. These compounds have various applications, including the manufacturing of fireworks, as a component in certain types of glass, and in the medical field for imaging purposes due to their radiopaque properties. Barium sulfate, for instance, is used as a contrast agent in X-ray imaging. Both sulfuric acid monoethyl ester and barium compounds have distinct properties and uses, with the former being an organic ester and the latter being inorganic substances with diverse industrial and medical applications.
The CAS Registry Mumber 6191-29-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,9 and 1 respectively; the second part has 2 digits, 2 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6191-29: (6*6)+(5*1)+(4*9)+(3*1)+(2*2)+(1*9)=93 93 % 10 = 3 So 6191-29-3 is a valid CAS Registry Number.
