Check Digit Verification of cas no

The CAS Registry Mumber 309-24-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,0 and 9 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 309-24:
(5*3)+(4*0)+(3*9)+(2*2)+(1*4)=50
50 % 10 = 0
So 309-24-0 is a valid CAS Registry Number.

Reactions of poly(hexafluoropropylene oxide) perfluoroisopropyl ketone with various amines

Howell, Jon L.,Friesen, Chadron M.,Laugesen, Krista L.,van der Ende, Alice E.

, p. 178 - 184 (2008/09/17)

The reaction of poly(hexafluoropropylene oxide) perfluoroisopropyl ketone, perfluoroethyl perfluoroisopropyl, or bis-perfluoroisopropyl ketone with various amines has been studied and the products identified. A comparison of the reactivity of the ketones with different amines is made and identified by mass spectroscopy. The reaction of diethyl amine with all three ketones leads to two unexpected products and the mechanism of their formation is considered.
