1141683-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1141683-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,1,6,8 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1141683-19:
(9*1)+(8*1)+(7*4)+(6*1)+(5*6)+(4*8)+(3*3)+(2*1)+(1*9)=133
133 % 10 = 3
So 1141683-19-3 is a valid CAS Registry Number.

Diastero- and enantioselective intramolecular carbometalation reaction
Unger, Rozalia,Cohen, Theodore,Marek, Ilan
experimental part, p. 4874 - 4881 (2010/08/13)
The zinc-catalyzed addition of various alkynes to acylsilanes followed by a Zn-Brook rearrangement and either the Zn-ene-allene or Zn-yne-allene cyclization led to the enantio- and diastereoselective formation of carbocycles in a single-pot operation.
