(8*8)+(7*7)+(6*1)+(5*8)+(4*4)+(3*1)+(2*2)+(1*8)=190
190 % 10 = 0
So 871841-28-0 is a valid CAS Registry Number.

Preparation of novel 3H-trifluoromethyldiazirine-based photoactivatable potassium channel antagonists

Sanderson, John M.,Findlay, John B. C.,Fishwick, Colin W. G.

, p. 11244 - 11252 (2007/10/03)

The preparation of a series of photoactivatable precursors for use in photoaffinity labelling of potassium channels is described. 3H-Diazirine functionalities were incorporated into the previously described potassium channel antagonists 1-3. The ability to perform enantioselective reductions and Wittig reactions in the presence of 3H-diazirines was central to this work.
