Check Digit Verification of cas no
The CAS Registry Mumber 187148-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,1,4 and 8 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 187148-77:
(8*1)+(7*8)+(6*7)+(5*1)+(4*4)+(3*8)+(2*7)+(1*7)=172
172 % 10 = 2
So 187148-77-2 is a valid CAS Registry Number.

Efficient synthesis of N-alkyl-2,7-dihalocarbazoles by simultaneous carbazole ring closure and N-alkylation
Vyprachticky, Drahomír,Kmínek, Ivan,Pokorná, Veronika,Cimrová, Věra
experimental part, p. 5075 - 5080 (2012/07/28)
The N-alkyl-2,7-dihalocarbazole as the main product was formed by the reaction of 4,4′-dihalo-2-nitrobiphenyl with aromatic nitro compound and trialkyl phosphite. The presence and crucial role of aromatic nitro compound causes simultaneous carbazole ring closure and N-alkylation unlike the Cadogan ring closure where non-alkylated carbazole is formed as a main product. In addition, the mixture of aromatic nitro compound and trialkyl phosphite was found to be a possible N-alkylating agent for heterocycles, such as carbazole or indole.
