Check Digit Verification of cas no

The CAS Registry Mumber 69054-34-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,5 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69054-34:
(7*6)+(6*9)+(5*0)+(4*5)+(3*4)+(2*3)+(1*4)=138
138 % 10 = 8
So 69054-34-8 is a valid CAS Registry Number.

Microwave-promoted TBAF-catalyzed SNAr reaction of aryl fluorides and ArSTMS: An efficient synthesis of unsymmetrical diaryl thioethers

Liu, Chuanzhi,Zang, Xufeng,Yu, Baohua,Yu, Xiaochun,Xu, Qing

supporting information; experimental part, p. 1143 - 1148 (2011/07/09)

Microwave irradiation was found to promote tetrabutylammonium fluoride catalyzed nucleophilic aromatic substitution of aryl fluorides and arylthiotrimethylsilanes, affording high yields of unsymmetrical diaryl thioethers efficiently under mild, transition-metal- and base-free conditions. Microwave showed unusual improvement on the reaction in not only the conditions and reaction rate, but also in selectivity and substrate scope. Georg Thieme Verlag Stuttgart - New York.
