2,3,4,5-tetra-O-acetyl-D-xylose diethyl dithioacetal is a complex organic compound derived from D-xylose, a pentose sugar. It is characterized by the presence of four acetyl groups (-COCH3) attached to the hydroxyl groups at the 2, 3, 4, and 5 positions of the xylose molecule, which protect the hydroxyl groups from unwanted reactions. Additionally, it features a diethyl dithioacetal group, which is a sulfur-containing protecting group that can be used to shield the aldehyde group at the 1-position of the sugar. 2,3,4,5-tetra-O-acetyl-D-xylose diethyl dithioacetal is often used in organic synthesis and carbohydrate chemistry as a protected form of D-xylose, allowing for selective reactions at specific functional groups while the rest of the molecule remains inert. The diethyl dithioacetal group can be selectively removed under mild conditions when needed, making 2,3,4,5-tetra-O-acetyl-D-xylose diethyl dithioacetal a valuable intermediate in the synthesis of various complex carbohydrates and their derivatives.

7226-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7226-49-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,2 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.Calculate Digit Verification of CAS Registry Number 7226-49:
(6*7)+(5*2)+(4*2)+(3*6)+(2*4)+(1*9)=95
95 % 10 = 5
So 7226-49-5 is a valid CAS Registry Number.
