Check Digit Verification of cas no

The CAS Registry Mumber 127594-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,5,9 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127594-97:
(8*1)+(7*2)+(6*7)+(5*5)+(4*9)+(3*4)+(2*9)+(1*7)=162
162 % 10 = 2
So 127594-97-2 is a valid CAS Registry Number.

Efficient Conversions of Thioethers to α-Fluoro Thioethers with DAST or DAST/Antimony(III) Chloride

Robins, Morris J.,Wnuk, Stanislaw F.

, p. 3800 - 3801 (2007/10/02)

Dialkyl or alkyl aryl thioethers, including nucleoside thioethers, undergo virtually quantitative conversion to α-fluoro thioethers with (diethylamino)sulfur trifluoride (DAST) in dichloromethane at ambient temperature.Antimony(III) chloride catalyzes the process.
