387819-85-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 387819-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,8,7,8,1 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 387819-85:
(8*3)+(7*8)+(6*7)+(5*8)+(4*1)+(3*9)+(2*8)+(1*5)=214
214 % 10 = 4
So 387819-85-4 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 (2001)
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.
