1235454-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1235454-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,5,4,5 and 4 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1235454-13:
(9*1)+(8*2)+(7*3)+(6*5)+(5*4)+(4*5)+(3*4)+(2*1)+(1*3)=133
133 % 10 = 3
So 1235454-13-3 is a valid CAS Registry Number.

Gold(I)-catalyzed intermolecular [2+2] cycloaddition of alkynes with alkenes
Lopez-Carrillo, Veronica,Echavarren, Antonio M.
, p. 9292 - 9294 (2010)
The gold(I)-catalyzed intermolecular reaction of terminal alkynes with alkenes leads to cyclobutenes. The use of sterically hindered cationic Au(I) complexes as catalysts is key for the success of this reaction.
