Check Digit Verification of cas no

The CAS Registry Mumber 219755-75-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,7,5 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219755-75:
(8*2)+(7*1)+(6*9)+(5*7)+(4*5)+(3*5)+(2*7)+(1*5)=166
166 % 10 = 6
So 219755-75-6 is a valid CAS Registry Number.

Catalyst-Free Sulfonylation of 2-Methoxyphenols: Facile One-Pot Synthesis of (Arylsulfonyl)catechols in Aqueous Media

Taneja, Neha,Peddinti, Rama Krishna

, p. 5306 - 5314 (2017)

A new water-assisted carbon–sulfur bond-formation strategy is described for direct access to highly valuable (arylsulfonyl)catechols. This scalable transformation is remarkable, as a tandem dearomatization/sulfonylation and hydroxylation process enabled t

Efficient synthesis and subsequent transformations of phenylsulfanylbicyclo[2.2.2]octenones and phenylselenylbicyclo[2.2.2]octenones

Gao, Shih-Yu,Chittimalla, Santhosh Kumar,Chuang, Gary Jing,Liao, Chun-Chen

supporting information; experimental part, p. 1632 - 1639 (2009/07/09)

Inverse-electron-demand Diels-Alder reactions of masked o-benzoquinones 2 with phenyl vinyl sulfide and phenyl vinyl selenide furnished highly functionalized bicyclo[2.2.2]octenone derivatives 3 and 4, respectively, in excellent regio- and stereoselectivities and yields up to 90%. The bicyclo[2.2.2]octenone derivatives 3 with the sulfur functionality were subjected to an oxidation-elimination process to furnish bicyclo[2.2.2] octadienone systems 7 in good yields. During the reduction process, the Diels-Alder adducts 3e and 4e led to 8, whereas the carbon-centered radicals generated from the other adducts 3a-d and 4a-d provided various rearranged products 9-13 depending on the substitution pattern and reagents utilized (Raney-Ni or n-Bu3SnH). Surprisingly these radicals showed preference for the carbonyl functionality to the olefinic double bond, leading to interesting rearrangement reactions of mechanistic importance and possible synthetic utility. Interestingly the alcohols obtained from the reduction of Diels-Alder adducts 3a-d underwent desulfurization smoothly to give desulfurized products in high yields; thus a detoured method of "reduction- desulfurization-oxidation" provides an entry to desulfurized bicyclo[2.2.2]octenones without rearrangement.

Cyclopropane ring-opening of tricyclo[3.3.0.02,8]octan-3-ones: a quick access to bicyclo[3.2.1]octanones from 2-methoxyphenols
