Calculate Digit Verification of CAS Registry Number 128042-30:
(8*1)+(7*2)+(6*8)+(5*0)+(4*4)+(3*2)+(2*3)+(1*0)=98
98 % 10 = 8
So 128042-30-8 is a valid CAS Registry Number.

VINYL ETHERS CONTAINING AN ISOTHIOCYANATE GROUP II, SYNTHESIS OF THE ACETALS OF ISOTHIOCYANATOETHANOL

Nedolya, N. A.,Gerasimova, V. V.,Papsheva, N. N.

, p. 2243 - 2249 (2007/10/02)

The reaction of the simplest alcohols with 2-vinyloxyethyl isothiocyanate under electrophilic conditions leads to previously unknown acetals containing an isothiocyanate group.Under the reaction conditions (0.2-1.3 wtpercent of perfluorobutyric acid, 40-80, 0.6-3 h) 1,3-oxazolidine-2-thione is formed in addition to the corresponding acetals.The conditions were found which make it possible to direct the reaction toward the preferential formation of either 1,3-oxazolidine-2-thione or the 2-isothiocyanatoethyl acetals of acetaldehyde.
