Check Digit Verification of cas no

The CAS Registry Mumber 1034307-07-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,4,3,0 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1034307-07:
(9*1)+(8*0)+(7*3)+(6*4)+(5*3)+(4*0)+(3*7)+(2*0)+(1*7)=97
97 % 10 = 7
So 1034307-07-7 is a valid CAS Registry Number.

An efficient synthesis of indolo[3,2-a]carbazoles via the novel acid catalyzed reaction of indoles and diaryl-1,2-diones

Nair, Vijay,Nandialath, Vidya,Abhilash, Keecherikunnel G.,Suresh, Eringathodi

experimental part, p. 1738 - 1742 (2008/10/09)

A mild and efficient one pot method for the synthesis of indolo[3,2-a]carbazole derivatives by the para-toluenesulfonic acid catalyzed condensation of indole with acyclic 1,2-diones is described. With cyclobutene-1,2-diones the reaction afforded indole substituted carbazole derivatives in good yield. The Royal Society of Chemistry.
