Check Digit Verification of cas no

The CAS Registry Mumber 22158-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,1,5 and 8 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 22158-95:
(7*2)+(6*2)+(5*1)+(4*5)+(3*8)+(2*9)+(1*5)=98
98 % 10 = 8
So 22158-95-8 is a valid CAS Registry Number.

Process for preparing cyclic N-vinylacylamines

-

, (2008/06/13)

Cyclic N-vinylacylamines are prepared by heating carbonic acid esters of cyclic N-2-hydroxyethylacylamines in the presence of a catalytic amount of alkali or alkaline earth metal compound having an alkaline reaction and subsequently distilling the reaction mixture. Cyclic N-vinylacylamines are valuable precursors for preparing plant protection agents and medicaments and serve as polymerization and copolymerization components for preparing plastics, surface coatings, paints and ion exchange materials.
