Check Digit Verification of cas no
The CAS Registry Mumber 17823-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,8,2 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 17823-40:
(7*1)+(6*7)+(5*8)+(4*2)+(3*3)+(2*4)+(1*0)=114
114 % 10 = 4
So 17823-40-4 is a valid CAS Registry Number.

Perfluorozinc aromatics by direct insertion of zinc into C-F or C-CL bonds
Miller, Alexey O.,Krasnov, Vyacheslav I.,Peters, Dietmar,Platonov, Vyacheslav E.,Miethchen, Ralf
, p. 3817 - 3819 (2007/10/03)
For the first time perfluoroaromatic organozinc compounds were obtained by direct action of zinc on C-F bonds in the presence of metal salts (SnCl2, CuCl2, ZnBr2). The reactions are accelerated by ultrasound. The scope of
