Check Digit Verification of cas no

The CAS Registry Mumber 1229244-49-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,9,2,4 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1229244-49:
(9*1)+(8*2)+(7*2)+(6*9)+(5*2)+(4*4)+(3*4)+(2*4)+(1*9)=148
148 % 10 = 8
So 1229244-49-8 is a valid CAS Registry Number.

Facile synthesis of 5H-benzo[b]carbazol-6-yl ketones via sequential reaction of Cu-catalyzed Friedel-Crafts alkylation, iodine-promoted cyclization, nucleophilic substitution and aromatization

Wu, Jing,Wang, Dongping,Wang, Haolong,Wu, Fan,Li, Xincheng,Wan, Boshun

supporting information, p. 6806 - 6811 (2014/09/30)

A convenient method to access 5H-benzo[b]carbazol-6-yl ketones via a sequential Cu-catalyzed Friedel-Crafts alkylation reaction of indoles with 2-(2-(alkynyl)benzylidene)malonates and iodine-promoted electrophilic cyclization followed by nucleophilic substitution and aromatization was developed. The products of the functional 5H-benzo[b]carbazol-6-yl ketones were obtained with up to 98% yield. This journal is the Partner Organisations 2014.
