Calculate Digit Verification of CAS Registry Number 89736-75:
(7*8)+(6*9)+(5*7)+(4*3)+(3*6)+(2*7)+(1*5)=194
194 % 10 = 4
So 89736-75-4 is a valid CAS Registry Number.

The photochemical addition of N-haloamides to olefins: a comparison of cyclic and acyclic N-halo-N-alkylamides and N-halo-N-acylamides (N-haloimides)

Lessard, Jean,Couture, Yvon,Mondon, Martine,Touchard, Daniel

, p. 105 - 112 (2007/10/02)

Upon photochemical decomposition in the presence of cyclohexene and 1-octene, an N-halo-N-acylamide (N-haloimide) leads to better yields of addition than its N-halo-N-alkyl analogue, and cyclic N-halo-N-alkyl and N-halo-N-acylamides add more efficiently than their acyclic analogues.The yields of addition were higher with N-chlorosuccinimide which has been added also to 1-methylcyclohexene than with N-bromosuccinimide which did not add to 1-methylcyclohexene.
