Check Digit Verification of cas no

The CAS Registry Mumber 769-78-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,6 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 769-78:
(5*7)+(4*6)+(3*9)+(2*7)+(1*8)=108
108 % 10 = 8
So 769-78-8 is a valid CAS Registry Number.

Novel synthesis routes for the preparation of low toxic vinyl ester and vinyl carbonate monomers

Hofecker, Andreas,Knaack, Patrick,Liska, Robert,Markovic, Marica,Ovsianikov, Aleksandr,Steinbauer, Patrick

supporting information, p. 3629 - 3641 (2020/10/02)

UV curing of photopolymerizable monomers, like (meth)acrylates, has been utilized for coatings for more than half a century and more recently in further developed areas such as tissue engineering. However, these monomers have major disadvantages, e.g., high irritancy and cytotoxicity, which leads to limited use in tissue engineering regarding health issues. Vinyl esters (VE) and vinyl carbonates (VC) can compete with (meth)acrylates in terms of material properties and have significantly lower toxicity, but lack in cost efficient synthesis methods. The purpose of this communication is to establish new pathways to overcome this drawback. It was shown that VEs can be synthesized either by vinyloxy trimethylsilane or by acetaldehyde in excellent yields. Moreover, a new method to synthesize vinyl chloroformate as precursor for VCs in lab scale was evolved by a catalyzed reaction of vinyloxy trimethylsilane with a phosgene solution. Finally, the cytotoxicity tests showed auspicious results.

Oxidative Dehydroxymethylation of Alcohols to Produce Olefins

-

Paragraph 0057; 0058, (2019/09/06)

Catalyst compositions for the conversion of aldehyde compounds and primary alcohol compounds to olefins are disclosed herein. Reactions include oxidative dehydroxymethylation processes and oxidative dehydroformylation methods, which are beneficially conducted in the presence of a sacrificial acceptor of H2 gas, such as N,N-dimethylacrylamide.

Eco-environmental synthesis of vinyl benzoate through transesterification catalyzed by Pd/C catalyst

Gao, Jun,Guan, Dongrui,Xu, Dongmei,Zhao, Liwen,Zhang, Lianzheng,Li, Min

, p. 351 - 359 (2018/09/06)

The synthesis of vinyl benzoate via transesterification of vinyl acetate with benzoic acid was investigated by a carbon-supported palladium catalyst. The results showed that Pd (5 wt %)/C catalyst presented good catalytic and reusable performance instead of mercuric salts of strong acids. The conditions of the transesterification reaction for achieving high yields of vinyl benzoate were explored. The optimized conditions are as follows: reaction temperature, 80°C, reaction time, 10 h, catalyst dosage, 4.0 wt % of reactants, and benzoic acid/vinyl acetate molar ratio, 1:11, respectively, and the yield of vinyl benzoate was 85.7% with the purity of 98.3%. Meanwhile, the prepared Pd/C catalyst could be recycled five times without significant decrease in activity after separating from the product mixture, and the vinyl benzoate yield is still more than 81%. Furthermore, the eco-environmental synthetic method offers great potential for the industrial scale synthesis of vinyl benzoate.
