Check Digit Verification of cas no
The CAS Registry Mumber 18028-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,0,2 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 18028-55:
(7*1)+(6*8)+(5*0)+(4*2)+(3*8)+(2*5)+(1*5)=102
102 % 10 = 2
So 18028-55-2 is a valid CAS Registry Number.

Synthesis of carbazoles from N-(N,N-diarylamino)phthalimides with aluminum chloride via diarylnitrenium ions
Kikugawa,Aoki,Sakamoto
, p. 8612 - 8615 (2007/10/03)
Generation of diarylnitrenium ions from N-(N,N-diarylamino)phthalimides by treatment with AlCl3 in benzene or in 1,2-dichloroethane leads to formation of carbazoles by intramolecular C-C bond formation. The reaction proceeds in synthetically useful yields.

Photolysis of 2-fluoro-2′,5′-dimethyldiphenylamine 1a, in ethanol with a medium-pressure mercury lamp, gave a mixture of 1,4-dimethylcarbazole 7 (53%), 8-fluoro-1,4-dimethylcarbazole 2 (11%) and 6-ethoxy-2-fluoro-2′,5′-dimethyldiphenylamine 8 (19%). Photolysis of 4-fluoro-2′,5′-dimethyldiphenylamine 1b gave 6-fluoro-1,4-dimethylcarbazole 25 (35%) and 1,4-dimethylcarbazole 7 (47%).
