(2R,3R)-2,3-diphenyl-1,4-butandiol-di-p-tosylat is a complex organic compound characterized by its chiral center, which gives it the (2R,3R) configuration. (2R,3R)-2,3-diphenyl-1,4-butandiol-di-p-tosylat consists of a butane backbone with two phenyl groups attached to the second and third carbon atoms, respectively. The 1,4-positions of the butane are occupied by hydroxyl groups, which are further substituted with p-toluenesulfonyl (tosyl) groups. The tosyl groups are significant as they can act as protecting groups for the hydroxyl groups, preventing unwanted reactions at these sites. (2R,3R)-2,3-diphenyl-1,4-butandiol-di-p-tosylat is of interest in organic synthesis, particularly in the preparation of chiral compounds and as a precursor in the synthesis of more complex molecules. Its structure allows for stereoselective reactions, making it a valuable tool in the field of asymmetric synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 24435-43-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,3 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24435-43:
(7*2)+(6*4)+(5*4)+(4*3)+(3*5)+(2*4)+(1*3)=96
96 % 10 = 6
So 24435-43-6 is a valid CAS Registry Number.
