68820-01-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 68820-01-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,8,2 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 68820-01:
(7*6)+(6*8)+(5*8)+(4*2)+(3*0)+(2*0)+(1*1)=139
139 % 10 = 9
So 68820-01-9 is a valid CAS Registry Number.

Regioselective ring-opening of aziridines with diselenides and disulfides using the Zn/AlCl3 system

Movassagh, Barahman,Morovat, Elaheh Salehi

experimental part, p. 117 - 122 (2012/01/04)

An efficient Zn/AlCl3-promoted highly regioselective one-pot procedure has been demonstrated for the synthesis of β-amino selenides and sulfides from a variety of diselenides/disulfides and aziridines by reductive cleavage of Se-Se and S-S bond

Pyrrolidines from olefins via radical cyclization

Gupta, Vijay,Besev, Magnus,Engman, Lars

, p. 2429 - 2432 (2007/10/03)

2,4-Disubstituted N-tosylpyrrolidines were prepared from olifeins via N- tosylaziridination, benseneselenolate ring-opening and reductive radical cyclization. Azidoselenation of olefins, followed by reduction, N-tosylation, N-allylation and reductive radical cyclization, afforded 3,4-disubstituted N- tosylpyrrolidines.
