219755-75-6 Usage

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

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

Chang, Chun-Ping,Chen, Ching-Hsien,Chuang, Gary Jing,Liao, Chun-Chen

supporting information; scheme or table, p. 3414 - 3417 (2009/09/28)

We herein report an efficient and rapid strategy for the synthesis of highly functionalized bicyclo[3.2.1]octanones via sequential reactions: Diels-Alder reaction of MOB-ODPM rearrangement-reductive cleavage of cyclopropane, and its application to synthes

The hetero Diels-Alder reactions of masked o-benzoquinones with nitroso compounds

Lin,Liao

, p. 1624 - 1625 (2007/10/03)

The first examples of hetero Diels-Alder reaction of masked o-benzoquinones with nitroso dienophiles leading to novel and highly functionalized heterocycles, which are potential intermediates for nitrogenous natural products are reported.
