Calculate Digit Verification of CAS Registry Number 1133034-67:
(9*1)+(8*1)+(7*3)+(6*3)+(5*0)+(4*3)+(3*4)+(2*6)+(1*7)=99
99 % 10 = 9
So 1133034-67-9 is a valid CAS Registry Number.

Terminal alkynes from aldehydes via dehydrohalogenation of (Z)-1-iodo-1-alkenes with TBAF

Beshai, Mira,Dhudshia, Bhartesh,Mills, Ryan,Thadani, Avinash N.

supporting information; experimental part, p. 6794 - 6796 (2009/04/07)

Terminal alkynes were prepared in near quantitative yields via dehydrohalogenation of (Z)-1-iodo-1-alkenes with tetrabutylammonium fluoride (TBAF) under mild conditions. The methodology was expanded to include a one-pot, direct synthesis of terminal alkynes from aldehydes without the necessity of isolating and purifying the intermediate iodoalkene.
