66487-37-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66487-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,8 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 66487-37:
(7*6)+(6*6)+(5*4)+(4*8)+(3*7)+(2*3)+(1*7)=164
164 % 10 = 4
So 66487-37-4 is a valid CAS Registry Number.

Perfluoroalkyl migration in the rearrangement of 4-perfluoroalkyl-4-quinols

Uno,Yayama,Suzuki

, p. 8353 - 8368 (2007/10/02)

Heating a DMSO solution of 4-(perfluoro-n-alkyl)-4-hydroxy-2,5-cyclohexadien-1-one (4-perfluoroalkyl-4-quinols) in the presence of a catalytic amount of base brought about 1,2-migration of the perfluoroalkyl group to give 2-(perfluoro-n-alkyl)hydroquinone

1,2-Migration of Perfluoroalkyl Groups in Anionotropic Rearrangement. The Acyloin Rearrangement of 4-Perfluoroalkyl-4-quinols

Uno, Hidemitsu,Yayama, Ayumi,Suzuki, Hitomi

, p. 1165 - 1168 (2007/10/02)

Treatment of 4-perfluoroalkyl-4-quinols with a catalytic amount of potassium t-butoxide gave 2-(perfluoroalkyl)hydroquinones or 5-perfluoroalkyl-2-cyclohexene-1,4-diones in good to moderate yields depending upon the substitution pattern of the quinols.Similarly, 2-hydroxy-3-methyl-2-perfluorooctyl-1-propyl-3-pyrrolin-5-one underwent the base-induced rearrangement to afford a perfluoroalkylated succinimide derivative.

Quinones. Part 10. Side-chain Methylthiolation of Methylbenzoquinones

Thomson, Ronald H.,Worthington, Roger D.

, p. 289 - 292 (2007/10/02)

2,3,5,6-Tetramethylbenzoquinone undergoes side-chain reaction with excess of sodium methanethiolate to form mono-, di-, and tri-methylthiomethyl derivatives in low yields. 2,5- and 2,6-Dimethylbenzoquinones react first on the nucleus to give dimethyl(dimethylthio)quinones followed by limited side-chain methylthiolation.The side-chain reaction is restricted by a competing redox reaction.The presence of semiquinone radical anions can be detected by selective line-broadening in the n.m.r. spectra of quinone-thiolate solutions.
