"O5-trityl-DL-1,4-anhydro-xylitol" is a complex organic compound with the molecular formula C31H34O5. It is a derivative of xylitol, a sugar alcohol, where the 1,4-anhydro-xylitol is a dehydrated form of xylitol, meaning it has lost a water molecule between the 1st and 4th carbon atoms. The "O5-trityl" part indicates that a trityl group (a bulky phenylmethyl group) is attached to the 5th oxygen atom of the xylitol backbone. This modification can affect the compound's reactivity, solubility, and other physical properties. The "DL" prefix signifies that the compound is a racemic mixture, containing equal parts of the D and L isomers, which are mirror images of each other. O5-trityl-DL-1,4-anhydro-xylitol is often used in organic synthesis and as a protecting group in carbohydrate chemistry due to its ability to shield certain functional groups from unwanted reactions.

Check Digit Verification of cas no

The CAS Registry Mumber 2159-29-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 9 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2159-29:
(6*2)+(5*1)+(4*5)+(3*9)+(2*2)+(1*9)=77
77 % 10 = 7
So 2159-29-7 is a valid CAS Registry Number.
