Check Digit Verification of cas no

The CAS Registry Mumber 133377-35-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,3,7 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133377-35:
(8*1)+(7*3)+(6*3)+(5*3)+(4*7)+(3*7)+(2*3)+(1*5)=122
122 % 10 = 2
So 133377-35-2 is a valid CAS Registry Number.

Synthesis of α-Trifluoromethylacrylates by Ligand-Free Palladium-Catalyzed Mizoroki-Heck Reaction

Xiao, Pan,Schlinquer, Claire,Pannecoucke, Xavier,Bouillon, Jean-Philippe,Couve-Bonnaire, Samuel

, (2019)

Efficient ligand-free palladium catalyzed Mizoroki-Heck reaction allowed the formation of trisubstituted α-trifluoromethylacrylates. The reaction showed good chemical tolerance and furnished moderate to excellent yields of reaction. Silver salt additive proved to be essential for the reaction. The reaction has been then applied to the formation of 3-trifluoromethyl coumarins and analogues of therapeutic agents.

A synthetic three fluoro methyl acrylic acid derivative method

-

Paragraph 0027; 0091-0093, (2017/03/28)

The invention relates to a novel method for synthesizing a derivative of trifluoromethyl acrylic acid. In the method, a target product with yield of more than 80% can be obtained with commercial trifluoropropionic acid (or esters thereof) and aldehyde as

Trifluoromethylation of alkenyl bromides and iodides (including 5-iodouracils) with (CF3)2Hg and Cu (" trifluoromethylcopper")

Nowak, Ireneusz,Robins, Morris J.

, p. 2678 - 2681 (2007/10/03)

Bromo- and iodoalkenes undergo trifluoromethylation efficiently in DMA with "CF3Cu" generated from (CF3)2Hg and Cu. Variable stereochemical inversion is observed with substrates having a gem-carbonyl group. Substrates having gem-hydrogen, -alkyl, or -alkenyl groups give products with stereochemical retention.
