"2,3:4,5-di-D-isopropylidene-D-xylose diethyl dithioacetal" is a complex organic compound with the molecular formula C16H30O4S2. It is a derivative of D-xylose, a pentose sugar, where the hydroxyl groups at positions 2 and 3, as well as 4 and 5, are protected by isopropylidene groups. The term "diethyl dithioacetal" indicates that two ethyl groups are attached to the molecule through dithioacetal linkages, which involve sulfur atoms. 2,3:4,5-di-D-isopropylidene-D-xylose diethyl dithioacetal is significant in organic synthesis as it represents a protected form of D-xylose, which can be used in the preparation of various complex carbohydrates and other biologically active molecules. The protection of the hydroxyl groups with isopropylidene and dithioacetal groups helps to prevent unwanted side reactions during synthesis, allowing for selective reactions at other sites on the molecule.

3673-14-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3673-14-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,7 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.Calculate Digit Verification of CAS Registry Number 3673-14:
(6*3)+(5*6)+(4*7)+(3*3)+(2*1)+(1*4)=91
91 % 10 = 1
So 3673-14-1 is a valid CAS Registry Number.
