1643-70-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1643-70-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1643-70:
(6*1)+(5*6)+(4*4)+(3*3)+(2*7)+(1*0)=75
75 % 10 = 5
So 1643-70-5 is a valid CAS Registry Number.

A new route to thio- and selenosulfonates from disulfides and diselenides. Application to the synthesis of new thio- and selenoesters of triflic acid

Billard, Thierry,Langlois, Bernard R.,Large, Sylvie,Anker, Daniel,Roidot, Nathalie,Roure, Philippe

, p. 7545 - 7550 (2007/10/03)

Alkyl and aryl trifluoromethanethiosulfonates1 (or selenosulfonates) were prepared in one step either from alkyl and aryl sulfenyl (or selenenyl) chlorides and sodium trifluoromethanesulfinate (3) or, more generally, from disulfides (or diselenides), 3, and bromine. The second method involved trifluoromethanesulfonyl bromide as key intermediate. Benzenethiosulfonates were obtained in a similar way from disulfides, benzenesulfinate, and bromine but benzeneselenosulfonates could not be obtained by the same method from diselenides.
