6572-95-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6572-95-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,5,7 and 2 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6572-95:
(6*6)+(5*5)+(4*7)+(3*2)+(2*9)+(1*5)=118
118 % 10 = 8
So 6572-95-8 is a valid CAS Registry Number.

A novel synthesis of cyclic polythioethers using liquid-liquid phase-transfer catalysis

Takido, Toshio,Toriyama, Masaharu,Ogura, Kazuhiro,Kamijo, Haruo,Motohashi, Shigeyasu,Seno, Manabu

, p. 1295 - 1301 (2007/10/03)

The synthesis of cyclic polythioethers has been achieved by the reactions of dithiols with alkyl dihalides. Thiols are not only hard to handle owing to their unpleasant smell, but also they are easily oxidizable, thus it is not easy to obtain various dithiols. However, we have developed a procedure for the preparation cyclic polythioethers by the reaction of dithioiminium salts with alkyl dihalides using phase-transfer catalyst without the use of dithiols, and have examined the ion recognition of these compounds.

A New Mode of Aromatic Substitution and Redox Reaction of Substituted Benzenes with Disulfide Dication: 1,5-Dithioniabicyclooctane Bis(trifluoromethanesulfonate)

Fujihara, Hisashi,Akaishi, Ryouichi,Furukawa, Naomichi

, p. 709 - 712 (2007/10/02)

Disulfide dication was found to react with several aromatics to give either the substitution or redox products.The rection mode depends remarkably on the oxidation potential of the aromatics.
