The chemical compound in question is a complex organic molecule with the systematic name "(1S)-O2,O4;O3,O5-(R,R)-dibenzylidene-1-(2,4-di-tert-butoxy-pyrimidin-5-yl)-D-ribitol." (1S)-O2,O4;O3,O5-(R,R)-dibenzylidene-1-(2,4-di-tert-butoxy-pyrimidin-5-yl)-D-ribitol features a chiral center at the ribitol moiety, indicated by the (1S) configuration, and a dibenzylidene bridge connecting two oxygen atoms. The pyrimidin-5-yl group is substituted at the 2,4-positions with tert-butoxy groups, which are bulky and provide steric hindrance. The compound's structure is characterized by the presence of multiple oxygen atoms involved in the formation of the dibenzylidene bridge and the connection to the pyrimidin-5-yl group. This molecule is likely to have unique chemical properties due to its complex structure and the presence of both aromatic and heterocyclic moieties.

Check Digit Verification of cas no

The CAS Registry Mumber 28455-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,5 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28455-50:
(7*2)+(6*8)+(5*4)+(4*5)+(3*5)+(2*5)+(1*0)=127
127 % 10 = 7
So 28455-50-7 is a valid CAS Registry Number.
