1237741-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1237741-50-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,7,7,4 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1237741-50:
(9*1)+(8*2)+(7*3)+(6*7)+(5*7)+(4*4)+(3*1)+(2*5)+(1*0)=152
152 % 10 = 2
So 1237741-50-2 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.
