1027919-53-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1027919-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,9,1 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027919-53:
(9*1)+(8*0)+(7*2)+(6*7)+(5*9)+(4*1)+(3*9)+(2*5)+(1*3)=154
154 % 10 = 4
So 1027919-53-4 is a valid CAS Registry Number.

Conversion of propargyl alcohols to chloroallenes and arylalkynes using the TiCl4/R3N reagent system
Karunakar, Galla V.,Periasamy, Mariappan
, p. 7463 - 7466 (2006)
Whereas the reaction of certain propargyl alcohols with TiCl4 in the presence of tertiary alkylamines gives the corresponding chloroallenes in 37-58% yields, reaction with the tertiary arylamines gives the corresponding arylalkynes in 68-77% yi
