Check Digit Verification of cas no

The CAS Registry Mumber 1027249-59-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,2,4 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1027249-59:
(9*1)+(8*0)+(7*2)+(6*7)+(5*2)+(4*4)+(3*9)+(2*5)+(1*9)=137
137 % 10 = 7
So 1027249-59-7 is a valid CAS Registry Number.

Lewis acid mediated one-pot synthesis of aryl/heteroaryl-fused carbazoles involving a cascade Friedel-Crafts alkylation/electrocyclization/aromatization reaction sequence

Sureshbabu, Radhakrishnan,Saravanan, Velu,Dhayalan, Vasudevan,Mohanakrishnan, Arasambattu K.

, p. 922 - 935 (2011/04/22)

A Lewis-acid-mediated domino reaction of 2/3-(bromomethyl)indoles with arenes/heteroarenes led to the formation of the corresponding annulated carbazoles. This three-step one-pot transformation proceeds by sequential Lewis acid catalysed Friedel-Crafts alkylation, electrocyclization and aromatization reactions. The strategy is highly efficient for the assembly of complex aryl/heteroaryl-fused carbazoles.
