1,2,3,4,6-penta-O-propionyl-β-D-glucopyranose is a complex organic compound derived from β-D-glucopyranose, a monosaccharide. It is characterized by the presence of five propionyl groups (ester-forming radicals derived from propionic acid) attached to the hydroxyl groups at positions 1, 2, 3, 4, and 6 of the glucopyranose ring. This chemical modification results in a derivative that is less hydrophilic and more lipophilic than the parent sugar, which can be useful in various applications, such as pharmaceuticals, where it may enhance the solubility or stability of the compound. The compound is synthesized by reacting β-D-glucopyranose with propionyl chloride or another propionylating agent, leading to the esterification of the hydroxyl groups. This derivative can be used as a building block in the synthesis of more complex carbohydrates or as a protecting group in organic synthesis to prevent unwanted reactions at the hydroxyl groups.

Check Digit Verification of cas no

The CAS Registry Mumber 642-02-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,4 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 642-02:
(5*6)+(4*4)+(3*2)+(2*0)+(1*2)=54
54 % 10 = 4
So 642-02-4 is a valid CAS Registry Number.
