Check Digit Verification of cas no

The CAS Registry Mumber 885679-09-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,5,6,7 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 885679-09:
(8*8)+(7*8)+(6*5)+(5*6)+(4*7)+(3*9)+(2*0)+(1*9)=244
244 % 10 = 4
So 885679-09-4 is a valid CAS Registry Number.

RCM-mediated synthesis of trifluoromethyl-containing nitrogen heterocycles

De Matteis, Valeria,Van Delft, Floris L.,Jakobi, Harald,Lindell, Stephen,Tiebes, Joerg,Rutjes, Floris P. J. T.

, p. 7527 - 7532 (2007/10/03)

(Chemical Equation Presented) A ring-closing metathesis mediated pathway to trifluoromethyl-containing piperidines is detailed. This involves the development of a synthetic route to a new (trifluoromethyl)allylating reagent via a Diels-Alder/retro-Diels-Alder strategy, its application in the synthesis of a series of trifluormethyl-substituted diolefin recursors for ring-closing metathesis, and eventually the successful cyclization of these precursor molecules into the corresponding functionalized piperidines.
