Check Digit Verification of cas no
The CAS Registry Mumber 2211-69-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,1 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2211-69:
(6*2)+(5*2)+(4*1)+(3*1)+(2*6)+(1*9)=50
50 % 10 = 0
So 2211-69-0 is a valid CAS Registry Number.

Surface-Catalyzed Reaction of the Gases Hydrogen Chloride and 2-Butyne
Mascavage, Linda M.,Zhang, Fan,Dalton, David R.
, p. 5048 - 5054 (1994)
Mixtures of gaseous hydrogen chloride and gaseous 2-butyne at total initial pressures less than 500 Torr, and at temperatures between 296 and 336 K, react in Pyrex IR cells (NaCl windows) to yield only (Z)-2-chloro-2-butene, i.e., the product of net trans (or anti or antarafacial) addition.Kinetic measurements have been made by observing the reaction throughout its course utilizing FT-IR spectroscopy.It is concluded that surface catalysis is required for product formation and that the reaction is occuring at the walls.
