Check Digit Verification of cas no

The CAS Registry Mumber 809237-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,9,2,3 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 809237-24:
(8*8)+(7*0)+(6*9)+(5*2)+(4*3)+(3*7)+(2*2)+(1*4)=169
169 % 10 = 9
So 809237-24-9 is a valid CAS Registry Number.

Polarity matching of radical trapping: High yielding 3-exo and 4-exo cyclizations

Gansaeuer, Andreas,Lauterbach, Thorsten,Geich-Gimbel, Daniel

, p. 4983 - 4990 (2007/10/03)

A catalyzed synthesis of cyclopropanes and cyclobutanes via radical chemistry is described. The method that generally proceeds in high yields uses epoxides as radical precursors and titanocene(III) complexes as the electron transfer catalysts (see scheme)
