3-bromo-2-pyridyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside is a complex organic compound that combines elements of pyridine, glucose, and bromine. 3-bromo-2-pyridyl 2,3,4,6-tetra-O-acetyl-β-D-glucopyranoside features a pyridine ring with a bromine atom at the 3-position and a glucose molecule in its β-D-glucopyranoside form, which is a common structural form of glucose. The glucose moiety is further modified by the presence of four acetyl groups, which are attached to the 2, 3, 4, and 6 positions of the glucose ring. These acetyl groups protect the hydroxyl groups of the glucose, which is a common strategy in organic chemistry to prevent unwanted reactions at these sites. The compound is likely used in the synthesis of more complex molecules or as a building block in medicinal chemistry, given its unique combination of functional groups.
The CAS Registry Mumber 4336-91-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,3 and 6 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 4336-91: (6*4)+(5*3)+(4*3)+(3*6)+(2*9)+(1*1)=88 88 % 10 = 8 So 4336-91-8 is a valid CAS Registry Number.
