Check Digit Verification of cas no
The CAS Registry Mumber 621-78-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 1 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 621-78:
(5*6)+(4*2)+(3*1)+(2*7)+(1*8)=63
63 % 10 = 3
So 621-78-3 is a valid CAS Registry Number.

Aliphatic thioethers by s-alkylation of thiols via trialkyl borates
Gunes, Deniz,Sirkecioglu, Okan,Bicak, Niyazi
body text, p. 1685 - 1690 (2010/09/17)
A simple and convenient one-pot procedure is described for the synthesis of thioethers via boron esters. This procedure involves in-situ generation of alkyl sulfates by reaction of trialkyl borates with concentrated sulfuric acid and subsequent reaction with thiols in the presence of pyridine. The reactions with boron esters of primary or secondary alcohols proceed cleanly at 100C and afford aliphatic thioethers in reasonable yields (59-93%) within 24 h. Interestingly, the 1H NMR spectra of the products showed no sign of positional isomerisms. The method fails however with thiophenol and does not yield aromatic thioethers, due to electrophilic substitution at the phenyl ring. Copyright Taylor & Francis Group, LLC.
