Check Digit Verification of cas no

The CAS Registry Mumber 13541-19-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13541-19:
(7*1)+(6*3)+(5*5)+(4*4)+(3*1)+(2*1)+(1*9)=80
80 % 10 = 0
So 13541-19-0 is a valid CAS Registry Number.

Redox-Neutral Tetrafluoroethylation of Aryl Alkynes with 1,1,2,2-Tetrafluoroethane Sulfonic Acid Leading to α-Tetrafluoroethylated Acetophenones

Kawamoto, Takuji,Noguchi, Kohki,Takata, Ryotaro,Sasaki, Rio,Matsubara, Hiroshi,Kamimura, Akio

, p. 9529 - 9534 (2021)

The redox-neutral tetrafluoroethylation of alkynes with 1,1,2,2-tetrafluroroethanesulfonic acid (TFESA) and azobis(isobutyronitrile) (AIBN) proceeds via the formation of vinyl tetrafluoroethanesulfonates followed by a radical tetrafluoroethylation. Experimental and theoretical results support an intermolecular reaction.

Cobalt-Tertiary-Amine-Mediated Hydroxytrifluoromethylation of Alkenes with CF3Br and Atmospheric Oxygen

Li, Qiankun,Fan, Wu,Peng, Deqian,Meng, Bingyin,Wang, Shaohan,Huang, Rui,Liu, Shihao,Li, Suhua

, p. 4012 - 4018 (2020/05/05)

The mild and efficient hydroxytrifluoromethylation of alkenes with bromotrifluoromethane (CF3Br) and atmospheric oxygen mediated by cobalt-tertiary amine is described. This reaction proceeds with broad substrate scope and good functional group compatibility. Mechanistic studies indicate that the reaction proceeds through a radical pathway, which is enabled by combination of the previously unexplored highly efficient N-isopropyl-N,2-dimethylpropan-2-amine with Co(II) for the single electron reduction of CF3Br to CF3 radical.

Catalyst-Free Oxytrifluoromethylation of Alkenes through Paired Electrolysis in Organic-Aqueous Media

Jud, Wolfgang,Kappe, C. Oliver,Cantillo, David

supporting information, p. 17234 - 17238 (2018/11/10)

A mild, catalyst-free electrochemical oxytrifluoromethylation of alkenes has been developed. The procedure is based on the paired electrolysis of sodium triflinate and water in an undivided cell. Anodic oxidation of the triflinate anion generates trifluoromethyl radicals that react with the alkene. Water plays a dual role as oxidant for the cathode and nucleophile. The method has been utilized to prepare a diverse set of 1-hydroxy-2-trifluoromethyl compounds in moderate to excellent yields (27–94 %). Alcohols have also been tested as nucleophiles for this versatile method with moderate yields. Facile recycling of the electrolyte has been demonstrated, and application of electricity avoids the use of stoichiometric amounts of oxidizers in a safe and environmentally benign reaction.
