"O4-Methyl-1,6;2,3-dianhydro-β-D-talopyranose" is a complex organic compound with the molecular formula C7H12O4. It is a derivative of β-D-talopyranose, a monosaccharide, where the hydroxyl group at the 4th carbon has been replaced by a methyl group (-CH3). The compound features a dianhydro structure, which means two hydroxyl groups have been removed, resulting in the formation of a double bond between the 1st and 6th carbon atoms, and another double bond between the 2nd and 3rd carbon atoms. This modification alters the reactivity and properties of the original sugar, potentially affecting its solubility, stability, and interaction with other molecules. It is often used in the synthesis of more complex organic compounds and can be found in various chemical and pharmaceutical applications.
The CAS Registry Mumber 6893-60-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,8,9 and 3 respectively; the second part has 2 digits, 6 and 0 respectively. Calculate Digit Verification of CAS Registry Number 6893-60: (6*6)+(5*8)+(4*9)+(3*3)+(2*6)+(1*0)=133 133 % 10 = 3 So 6893-60-3 is a valid CAS Registry Number.
