Check Digit Verification of cas no
The CAS Registry Mumber 21461-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,6 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 21461-78:
(7*2)+(6*1)+(5*4)+(4*6)+(3*1)+(2*7)+(1*8)=89
89 % 10 = 9
So 21461-78-9 is a valid CAS Registry Number.

Microwave-assisted solvent-free Diels-Alder reaction - A fast and simple route to various 5,6-substituted norbornenes and polychlorinated norbornenes
Dejmek, Milan,Hrebabecky, Hubert,Sala, Michal,Drainsky, Martin,Nencka, Radim
experimental part, p. 4077 - 4083 (2012/01/05)
A series of 5,6-substituted norbornenes and 5,6-substituted polychlorinated norbornenes was prepared by using a microwave-assisted Diels-Alder reaction. This procedure proved very versatile, fast, and with an easy workup step, and therefore suitable even for large-scale synthesis. Georg Thieme Verlag Stuttgart · New York.
