"DL-O1,O3;O2,O4-dimethanediyl-xylitol" is a complex organic compound with a unique structure. It is a derivative of xylitol, a sugar alcohol, with two methanediyl groups (-CH2-) bridging specific hydroxyl groups on the xylitol molecule. The "DL" prefix indicates that the compound is a racemic mixture, meaning it contains equal amounts of both the D and L enantiomers. The numbers in the compound's name (O1, O3; O2, O4) specify the positions of the hydroxyl groups that are involved in the formation of the methanediyl bridges. DL-O1,O3;O2,O4-dimethanediyl-xylitol is likely to be of interest in the field of organic chemistry, particularly in the synthesis of complex molecules and the study of chiral compounds.
The CAS Registry Mumber 5348-91-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,4 and 8 respectively; the second part has 2 digits, 9 and 1 respectively. Calculate Digit Verification of CAS Registry Number 5348-91: (6*5)+(5*3)+(4*4)+(3*8)+(2*9)+(1*1)=104 104 % 10 = 4 So 5348-91-4 is a valid CAS Registry Number.
