Check Digit Verification of cas no

The CAS Registry Mumber 913563-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,3,5,6 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 913563-89:
(8*9)+(7*1)+(6*3)+(5*5)+(4*6)+(3*3)+(2*8)+(1*9)=180
180 % 10 = 0
So 913563-89-0 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.
