Check Digit Verification of cas no

The CAS Registry Mumber 1609211-31-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,2,1 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1609211-31:
(9*1)+(8*6)+(7*0)+(6*9)+(5*2)+(4*1)+(3*1)+(2*3)+(1*1)=135
135 % 10 = 5
So 1609211-31-5 is a valid CAS Registry Number.

Synthesis of carbazoles by copper-catalyzed intramolecular C-H/N-H coupling

Takamatsu, Kazutaka,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro

, p. 2892 - 2895 (2014)

A Cu-catalyzed intramolecular C-H amination for the synthesis of carbazoles has been developed. The key to success is the installation of the picolinamide-based directing group, which is spontaneously removed after the coupling event. The Cu catalysis proceeded smoothly under Pd- and I(III)-free conditions, and its mild oxidation aptitude enables the rapid and concise construction of heteroatom-incorporated carbazole core π-systems.
