2,3,5-Tri-O-benzyl-4-O-p-toluoyl-D-arabinose-diethyldithioacetal is a complex organic compound with the molecular formula C41H48O6S2. It is a derivative of D-arabinose, a naturally occurring pentose sugar, with three benzyl groups attached to the 2, 3, and 5 positions, a p-toluoyl group at the 4 position, and a diethyldithioacetal protecting group. 2,3,5-Tri-O-benzyl-4-O-p-toluoyl-D-arabinose-diethyldithioacetal is used in organic synthesis, particularly in the preparation of complex carbohydrates and glycoconjugates, due to its ability to protect the hydroxyl groups of the sugar moiety during chemical reactions. The diethyldithioacetal group is a common protecting group for hydroxyl groups, which can be selectively removed under mild conditions to regenerate the free hydroxyl group. The benzyl and p-toluoyl groups provide additional protection and steric hindrance, which can be useful in controlling the reactivity of the molecule in various synthetic transformations.

4263-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4263-36-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,6 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.Calculate Digit Verification of CAS Registry Number 4263-36:
(6*4)+(5*2)+(4*6)+(3*3)+(2*3)+(1*6)=79
79 % 10 = 9
So 4263-36-9 is a valid CAS Registry Number.
