2,3,4,5-tetra-O-acetyl-D-arabinoyl chloride is a complex organic compound with the molecular formula C14H17ClO8. It is a derivative of D-arabinose, a pentose sugar, where the hydroxyl groups at positions 2, 3, 4, and 5 are acetylated, and the molecule is further modified with a chloroformyl group. 2,3,4,5-tetra-O-acetyl-D-arabinoyl chloride is often used in organic synthesis, particularly in the preparation of various arabinose derivatives and other complex carbohydrates. Its acetylated nature provides protection for the hydroxyl groups, which can be removed under specific conditions when needed, making it a valuable intermediate in the synthesis of biologically active molecules and pharmaceuticals.
The CAS Registry Mumber 3555-02-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,5 and 5 respectively; the second part has 2 digits, 0 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3555-02: (6*3)+(5*5)+(4*5)+(3*5)+(2*0)+(1*2)=80 80 % 10 = 0 So 3555-02-0 is a valid CAS Registry Number.
