Check Digit Verification of cas no
The CAS Registry Mumber 42739-26-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,7,3 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 42739-26:
(7*4)+(6*2)+(5*7)+(4*3)+(3*9)+(2*2)+(1*6)=124
124 % 10 = 4
So 42739-26-4 is a valid CAS Registry Number.

Ruthenium-Catalyzed Selective Addition of Carboxylic Acids to Alkynes.A Novel Synthesis of Enol Esters
Mitsudo, Take-aki,Hori, Yoji,Yamakawa, Yasushi,Watanabe, Yoshihisa
, p. 2230 - 2239 (2007/10/02)
Carboxylic acids react with alkynes in the presence of a catalytic amount of bis(ν5-cyclooctadienyl)ruthenium/trialkylphosphine/maleic anhydride in toluene at 60-80 deg.C to give enol esters having a terminal methylene group in good to excellent yields with high regioselectivity.The deuterium distributions in the products of the reaction of acetic acid-d with 1-hexyne and ethyl propargyl carbonate were examined.Kinetic measurments revealed that the rate has first-order dependence on carboxylic acid, alkyne, and the initial concentration of the ruthenium catalyst.
