Check Digit Verification of cas no

The CAS Registry Mumber 1219937-63-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,9,3 and 7 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1219937-63:
(9*1)+(8*2)+(7*1)+(6*9)+(5*9)+(4*3)+(3*7)+(2*6)+(1*3)=179
179 % 10 = 9
So 1219937-63-9 is a valid CAS Registry Number.

A new access to the 6,8-dioxabicyclo[3.2.1]octane ring system using a three-component reaction: Enantioselective synthesis of (+)-iso- exo -brevicomin

Bouziane, Asmae,Régnier, Thomas,Carreaux, Fran?ois,Carboni, Bertrand,Bruneau, Christian,Renaud, Jean-Luc

experimental part, p. 207 - 210 (2010/04/02)

The combination of a catalytic hetero-Diels-Alder-allylboration sequence and a ruthenium-catalyzed isomerization of an allylic alcohol moiety as key steps open a new route for the asymmetric synthesis of 6,8-dioxabicyclo[3.2.1] octane subunits. The application of this strategy to the synthesis of (+)-iso-exo-brevicomin is also reported. Georg Thieme Verlag Stuttgart - New York.
