Check Digit Verification of cas no
The CAS Registry Mumber 5469-36-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,6 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5469-36:
(6*5)+(5*4)+(4*6)+(3*9)+(2*3)+(1*6)=113
113 % 10 = 3
So 5469-36-3 is a valid CAS Registry Number.

Synthesis of maleic anhydrides and maleic acids by Pd-catalyzed oxidative dicarbonylation of alk-1-ynes
Gabriele, Bartolo,Veltri, Lucia,Salerno, Giuseppe,Costa, Mirco,Chiusoli, Gian Paolo
, p. 1722 - 1728 (2007/10/03)
We have found that carbon dioxide effectively promotes the Pd-catalyzed oxidative carbonylation of terminal alkynes to give maleic anhydrides in fair yields. Reactions were carried out in aqueous dioxane at 60-80 °C in the presence of catalytic amounts of PdI2 in conjunction with KI and under a 4:1:10 mixture of CO/air/CO2 (60 atm total pressure at 25 °C). By working in the presence of a large excess of water, maleic acids were formed selectively with unprecedented catalytic efficiencies for this kind of reaction. In the latter case, the use of an excess of carbon dioxide tended to inhibit, rather than promote, the reaction. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
