Check Digit Verification of cas no
The CAS Registry Mumber 104683-16-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,6,8 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 104683-16:
(8*1)+(7*0)+(6*4)+(5*6)+(4*8)+(3*3)+(2*1)+(1*6)=111
111 % 10 = 1
So 104683-16-1 is a valid CAS Registry Number.

One-pot synthesis of aryl sulfones from alcohols
Murakami, Teiichi,Furusawa, Kiyotaka
, p. 479 - 482 (2007/10/03)
A one-pot synthesis of aryl sulfones from primary alcohols is described. Alcohols were treated with N-bromosuccinimide and triphenylphosphine, followed by addition of sodium arenesulfinate with a catalytic amount of tetrabutylammonium iodide to afford the aryl sulfones in good to high yields.
