Check Digit Verification of cas no

The CAS Registry Mumber 229020-81-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,0,2 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 229020-81:
(8*2)+(7*2)+(6*9)+(5*0)+(4*2)+(3*0)+(2*8)+(1*1)=109
109 % 10 = 9
So 229020-81-9 is a valid CAS Registry Number.

Syntheses of 6-substituted indolo[3,2-b]carbazoles, including 6- formylindolo[3,2-b]carbazole, an extremely efficient ligand for the TCDD (Ah) receptor

Tholander, Joakim,Bergman, Jan

, p. 6243 - 6260 (1999)

A number of 6-substituted indolo[3,2-b]carbazoles have been synthesized using 2,3-diindolylmethane 5 as a crucial precursor. Most notably, 6- formylindolo[3,2-b]carbazole 3 has been synthesized, and thereby a previously assigned structure has been confirmed. 6-Formylindolo[3,2-b]carbazole 3 is an extremely efficient ligand for the TCDD (Ah) receptor. A much improved synthesis of 2,3-diindolylmethane 5 has also been developed.
