α-D-glucopyranose 1,2,4-orthoacetate is a complex carbohydrate derivative, specifically a glycoside, where the hydroxyl groups at positions 1, 2, and 4 of the α-D-glucopyranose molecule have been substituted with acetate groups. This chemical modification can alter the reactivity and solubility of the sugar, making it useful in various chemical and biological applications. The orthoacetate group is a bulky protecting group that can be used to shield specific functional groups during synthetic reactions, and it can be removed under mild conditions to regenerate the original hydroxyl groups. α-D-glucopyranose 1,2,4-orthoacetate is of interest in the fields of organic synthesis, carbohydrate chemistry, and biochemistry, where it may be employed to study the effects of chemical modifications on the biological activity of sugars or to develop new methods for the synthesis of complex carbohydrate structures.

Check Digit Verification of cas no

The CAS Registry Mumber 55911-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,9,1 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 55911-85:
(7*5)+(6*5)+(5*9)+(4*1)+(3*1)+(2*8)+(1*5)=138
138 % 10 = 8
So 55911-85-8 is a valid CAS Registry Number.
