Tris-O-(toluene-4-sulfonyl)-2,5-anhydro-D-arabitol is a complex organic compound with the molecular formula C36H39O15S3. It is a derivative of D-arabitol, a sugar alcohol, where three hydroxyl groups are replaced by tosyl (toluene-4-sulfonyl) groups. This modification is often used in organic synthesis to protect hydroxyl groups, which can be crucial in multi-step reactions to prevent unwanted side reactions. The compound is characterized by its ability to stabilize intermediates and control the reactivity of functional groups. It is used in various chemical reactions, particularly in the field of carbohydrate chemistry, to facilitate the synthesis of complex molecules by temporarily blocking certain reactive sites. The tosyl groups can be removed under specific conditions when the protection is no longer needed, allowing for further modification of the molecule.

15817-54-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 15817-54-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,8,1 and 7 respectively; the second part has 2 digits, 5 and 4 respectively.Calculate Digit Verification of CAS Registry Number 15817-54:
(7*1)+(6*5)+(5*8)+(4*1)+(3*7)+(2*5)+(1*4)=116
116 % 10 = 6
So 15817-54-6 is a valid CAS Registry Number.
