67399-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67399-71-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,3,9 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67399-71:
(7*6)+(6*7)+(5*3)+(4*9)+(3*9)+(2*7)+(1*1)=177
177 % 10 = 7
So 67399-71-7 is a valid CAS Registry Number.

COOLIGOMERIZATION OF PROPADIENE WITH PROPYNE CATALYSED BY NICKEL(0) COMPLEXES

Cermak, Jan,Blechta, Vratislav,Chvalovsky, Vaclav

, p. 1274 - 1286 (2007/10/02)

Cooligomerization of propadiene with propyne catalysed by bis(1,5-cyclooctadiene)nickel and tetrakis(triphenylphosphine)nickel gives a variety of products, including besides the cooligomers also the homooligomers of both monomers.The type of catalyst affects partially the product distribution due to changes in the degree of oligomerization.Cooligomerization of propadiene with 3-deuteriopropyne provided information about relative proportion of propadiene and propyne units in the oligomers.

SOME CATALYTIC PROPERTIES OF Rh(diphos)(η-BPh4)

Albano, P.,Aresta, M.

, p. 243 - 246 (2007/10/02)

The covalent complex Rh(diphos)(η-BPh4) (I) reacts with CO in polar solvents to afford the cationic dicarbonyl cis-(BPh4).I is an effective catalyst for methylacetylene oligomerization and allene polymerization.In the presence of CO2 and methylacetylene, I affords 4,6-dimethyl-2-pyrone.
