(4-iodo-phenyl)-β-D-glucopyranoside is a chemical compound consisting of a 4-iodophenyl group attached to a β-D-glucopyranose moiety. (4-iodo-phenyl)-β-D-glucopyranoside is a derivative of phenol, where one of the hydrogen atoms on the phenyl ring is replaced by an iodine atom, and it is glycosidically linked to a β-D-glucose molecule. The presence of the iodine atom makes (4-iodo-phenyl)-β-D-glucopyranoside potentially useful in various chemical reactions, such as those involving electrophilic aromatic substitution, due to the activating effect of the iodine. The β-D-glucopyranoside part of the molecule indicates that the glucose is in its pyranose form with the anomeric carbon (the one that was originally attached to the hydroxyl group) in the β-configuration. This specific stereochemistry is important for understanding how the compound may interact with enzymes or other biomolecules in biological systems. Overall, (4-iodo-phenyl)-β-D-glucopyranoside is a complex molecule that combines the properties of an aromatic iodide with those of a sugar, which could have applications in the fields of organic synthesis, medicinal chemistry, and biochemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 20838-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,8,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20838-40:
(7*2)+(6*0)+(5*8)+(4*3)+(3*8)+(2*4)+(1*0)=98
98 % 10 = 8
So 20838-40-8 is a valid CAS Registry Number.
