Check Digit Verification of cas no

The CAS Registry Mumber 1313900-30-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,3,9,0 and 0 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1313900-30:
(9*1)+(8*3)+(7*1)+(6*3)+(5*9)+(4*0)+(3*0)+(2*3)+(1*0)=109
109 % 10 = 9
So 1313900-30-9 is a valid CAS Registry Number.

N-Arylation of carbazole by microwave-assisted ligand-free catalytic CuI reaction

Kwon, Jae Kwan,Cho, Joong Hyun,Ryu, Young-Sil,Oh, Se Hwan,Yum, Eul Kgun

experimental part, p. 4820 - 4825 (2011/07/31)

N-Arylation of carbazole has been achieved in high yields within 1 h using a microwave-assisted catalytic CuI reaction with no organic ligand. The N-arylation can be performed by various arylhalides, such as phenyl, pyridine, thiophene, and thiazole moieties. Specifically, N-arylated bromocarbazoles were converted into useful synthetic intermediates for functionalized carbazole materials.
