Check Digit Verification of cas no

The CAS Registry Mumber 1028041-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,0,4 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1028041-91:
(9*1)+(8*0)+(7*2)+(6*8)+(5*0)+(4*4)+(3*1)+(2*9)+(1*1)=109
109 % 10 = 9
So 1028041-91-9 is a valid CAS Registry Number.

A potential route to neuroprostanes and isoprostanes: Preparation of the four enantiomerically pure diastereomers of 13-F4t-NeuroP

Taber, Douglass F.,Reddy, P. Ganapati,Arneson, Kyle O.

, p. 3467 - 3474 (2008/09/21)

(Chemical Equation Presented) We report a potential synthetic route to the isoprostanes and the neuroprostanes that could allow ready access to each of the enantiomerically pure diastereomers of the several regioisomers of these important human metabolites. The key transformation in the synthesis is a highly diastereoselective thermal intramolecular ene reaction. A critical observation is that the four enantiomerically pure diastereomers of an intermediate acetylenic ester are easily separated from one another. Each of these four has been carried on to a different enantiomerically pure diastereomer of 13-F 4t-neuroprostane.
