The chemical compound "DL-O1,O3;O2,O4-((RS,SR)-dibenzylidene)-O5-(toluene-4-sulfonyl)-xylitol" is a complex organic molecule with a unique structure. It features a xylitol core, which is a sugar alcohol, with various functional groups attached to it. The "DL" prefix indicates that the compound is a racemic mixture, meaning it contains equal amounts of both the R and S enantiomers. The "O1,O3;O2,O4" part of the name suggests that there are two sets of hydroxyl groups (OH) involved in the formation of the dibenzylidene acetal, which is a protective group for the hydroxyl groups. The "O5" refers to the hydroxyl group that is substituted with a toluene-4-sulfonyl group, which is a sulfonate ester derived from toluene. DL-O1,O3;O2,O4-((RS,SR)-dibenzylidene)-O5-(toluene-4-sulfonyl)-xylitol is likely used in organic synthesis, particularly in the protection of hydroxyl groups during complex reactions, and the toluene-4-sulfonyl group may serve as a handle for further functionalization or as a protecting group that can be selectively removed under certain conditions.

4321-74-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4321-74-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,2 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.Calculate Digit Verification of CAS Registry Number 4321-74:
(6*4)+(5*3)+(4*2)+(3*1)+(2*7)+(1*4)=68
68 % 10 = 8
So 4321-74-8 is a valid CAS Registry Number.
