Check Digit Verification of cas no

The CAS Registry Mumber 1399743-41-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,9,7,4 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1399743-41:
(9*1)+(8*3)+(7*9)+(6*9)+(5*7)+(4*4)+(3*3)+(2*4)+(1*1)=219
219 % 10 = 9
So 1399743-41-9 is a valid CAS Registry Number.

A facile synthesis of indolo[3,2,1-jk]carbazoles via palladium-catalyzed intramolecular cyclization

Lv, Jun,Liu, Qiancai,Tang, Jie,Perdih, Franc,Kranjc, Kristof

, p. 5248 - 5252 (2012/10/30)

A new efficient synthesis of indolo[3,2,1-jk]carbazoles by the palladium-catalyzed cyclization of N-(2-bromoaryl)carbazoles is described. The reaction involves intramolecular C-C bond formation, coupled with the cleavage of a C-X bond and a C-H bond on carbazole ring. Substitutions on N-aryl core with either electron-donating or electron-withdrawing groups are introduced, and different reaction factors for cyclization are evaluated.
