1263863-05-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1263863-05-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,8,6 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1263863-05:
(9*1)+(8*2)+(7*6)+(6*3)+(5*8)+(4*6)+(3*3)+(2*0)+(1*5)=163
163 % 10 = 3
So 1263863-05-3 is a valid CAS Registry Number.

Gold nanoparticles supported on TiO2 catalyse the cycloisomerisation/oxidative dimerisation of aryl propargyl ethers

Efe, Christina,Lykakis, Ioannis N.,Stratakis, Manolis

supporting information; body text, p. 803 - 805 (2011/04/12)

Gold nanoparticles supported on TiO2 (～1%) catalyse in high yields the selective cycloisomerisation of aryl propargyl ethers into the corresponding 2H-chromenes, under heterogeneous conditions. 2H,2′H-3, 3′-Bichromenes resulting from a catalytic oxidative dimerization pathway are also formed as by-products.
