2,3,5,6-Tetraacetoxy-acetophenon, also known as 2,3,5,6-Tetra-O-acetyl-D-glucal, is a chemical compound derived from D-glucal, a monosaccharide. It is a colorless, crystalline solid that is widely used in organic synthesis, particularly in the preparation of various glycosides and other carbohydrate derivatives. The compound is characterized by the presence of four acetoxy groups (-OAc) attached to the carbon atoms at positions 2, 3, 5, and 6, which protect the hydroxyl groups and facilitate further chemical reactions. Due to its reactivity and versatility, 2,3,5,6-tetraacetoxy-acetophenon serves as an important intermediate in the synthesis of complex carbohydrate structures, pharmaceuticals, and other bioactive compounds.
The CAS Registry Mumber 6172-62-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,7 and 2 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6172-62: (6*6)+(5*1)+(4*7)+(3*2)+(2*6)+(1*2)=89 89 % 10 = 9 So 6172-62-9 is a valid CAS Registry Number.
