1243602-19-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1243602-19-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,3,6,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1243602-19:
(9*1)+(8*2)+(7*4)+(6*3)+(5*6)+(4*0)+(3*2)+(2*1)+(1*9)=118
118 % 10 = 8
So 1243602-19-8 is a valid CAS Registry Number.

Gold-catalyzed intermolecular oxidation of o-alkynylbiaryls: An easy and practical access to functionalized fluorenes

Pan, Fei,Liu, Shuang,Shu, Chao,Lin, Rong-Kun,Yu, Yong-Fei,Zhou, Jin-Mei,Ye, Long-Wu

, p. 10726 - 10729 (2014)

A novel gold-catalyzed intermolecular oxidation of o-alkynylbiaryls has been developed. A variety of functionalized fluorenes are readily accessed by utilizing this non-diazo approach, thus providing a viable alternative to synthetically useful fluorenes. This journal is the Partner Organisations 2014.

Palladium catalyzed tandem alkenyl- and aryl-C-N bond formation: A cascade N-annulation route to 4-, 5-, 6- and 7-chloroindoles

Henderson, Luke C.,Lindon, Matthew J.,Willis, Michael C.

experimental part, p. 6632 - 6638 (2010/10/03)

A series of trihalogenated alkenylbenzenes undergo consecutive palladium catalyzed inter- and intramolecular amination reactions to deliver a series of 1-functionalized mono-chloroindoles. 4-, 5-, 6- and 7-Chloroindoles can all be prepared; carbamates, anilines and amines can be employed as the N-nucleophile.
