The CAS Registry Mumber 1243601-90-2 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 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1243601-90:
(9*1)+(8*2)+(7*4)+(6*3)+(5*6)+(4*0)+(3*1)+(2*9)+(1*0)=122
122 % 10 = 2
So 1243601-90-2 is a valid CAS Registry Number.

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.
