96898-10-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 96898-10-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,8,9 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 96898-10:
(7*9)+(6*6)+(5*8)+(4*9)+(3*8)+(2*1)+(1*0)=201
201 % 10 = 1
So 96898-10-1 is a valid CAS Registry Number.

Silver-mediated trifluoromethoxylation of aryl stannanes and arylboronic acids

Huang, Chenghong,Liang, Theresa,Harada, Shinji,Lee, Eunsung,Ritter, Tobias

supporting information; experimental part, p. 13308 - 13310 (2011/10/10)

A silver-mediated cross-coupling of trifluoromethoxide with aryl stannanes and arylboronic acids to give aryl trifluoromethyl ethers is reported. This is the first report of a transition-metal-mediated Caryl-OCF3 bond formation.

Versatile application of trifluoromethyl triflate

Kolomeitsev, Alexander A.,Vorobyev, Mikhail,Gillandt, Hartmut

, p. 449 - 454 (2008/09/18)

Hydrolytically stable and easy to handle trifluoromethyl triflate was found to be a liquid reservoir of 'masked' difluorophosgene. Anhydrous F- sources cleave the S-O bond in trifluoromethyl triflate yielding quantitatively the trifluoromethanolate salts, being useful trifluoromethoxy group carriers. Reaction of trifluoromethanolates with in situ generated from o-trimethylsilylphenyl triflate benzyne leads to (trifluoromethoxy)benzene and fluorobenzene (ratio 85:15). Whereas an addition of trifluoromethanethiolate anion across a triple bond of benzyne leads to [(trifluoromethyl)sulfanyl]benzene solely.
