Check Digit Verification of cas no

The CAS Registry Mumber 1620673-69-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,0,6,7 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1620673-69:
(9*1)+(8*6)+(7*2)+(6*0)+(5*6)+(4*7)+(3*3)+(2*6)+(1*9)=159
159 % 10 = 9
So 1620673-69-9 is a valid CAS Registry Number.

DMSO/iodine-catalyzed oxidative C-Se/C-S bond formation: A regioselective synthesis of unsymmetrical chalcogenides with nitrogen- or oxygen-containing arenes

Saba, Sumbal,Rafique, Jamal,Braga, Antonio L.

, p. 3087 - 3098 (2016)

A convenient metal-free and solvent-free iodine-catalyzed regioselective greener protocol to access different types of unsymmetrical chalcogenides with nitrogen- or oxygen-containing arenes through oxidative C-Se/C-S formation via direct C(sp2)-H bond activation was developed. The products were obtained in good to excellent yields using [O or N]-containing arenes, half equiv. of various odorless diorganyl dichalcogenides (S/Se), iodine (20 mol%) as the catalyst and 3 equiv. of DMSO as the oxidant, applying MW irradiation for 10 min.

Rose Bengal catalysed photo-induced selenylation of indoles, imidazoles and arenes: A metal free approach

Saba, Sumbal,Rafique, Jamal,Franco, Marcelo S.,Schneider, Alex R.,Espíndola, Leandro,Silva, Dagoberto O.,Braga, Antonio L.

supporting information, p. 880 - 885 (2018/02/19)

In this report, the highly efficient Rose Bengal-catalysed C(sp2)-H selenylation of indoles, imidazoles and arenes was achieved using a half molar equiv. of diorganoyl diselenides. This metal-free, photo-induced protocol resulted in selenylated

Metal and base-free synthesis of arylselanyl anilines using glycerol as a solvent

Thurow,Penteado,Perin,Jacob,Alves,Lenardao

supporting information, p. 3854 - 3859 (2014/08/05)

We describe here a metal and base-free straightforward method to access arylselanyl anilines using glycerol as a solvent. Starting from N,N-disubstituted anilines and arylselanyl chloride, the protocol is general and was successfully applied to a sort of anilines with different substitution patterns in both the aromatic ring and the nitrogen atom. As desirable for a green synthetic procedure, the non-toxic, low volatile, renewable glycerol was used as a solvent at room temperature. This journal is the Partner Organisations 2014.
