Calculate Digit Verification of CAS Registry Number 1199-81:
(6*1)+(5*1)+(4*9)+(3*9)+(2*8)+(1*1)=91
91 % 10 = 1
So 1199-81-1 is a valid CAS Registry Number.

Glebov,Kliger,Shuikin,Zaikin

, p. 346 - 352 (2007/10/03)

A study has been made of the vapour-phase reaction of tetrahydrofurfuryl alcohol with ammonia and hydrogen on Cu-, Ni-, Co- and Fe-containing bifunctional catalysts at a temperature of 180-240°C. It has been established that, irrespective of the type of catalyst, the main reaction products are piperidine, tetrahydrofurfurylamine and their derivatives. Copyright
