Check Digit Verification of cas no

The CAS Registry Mumber 139746-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,4 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139746-23:
(8*1)+(7*3)+(6*9)+(5*7)+(4*4)+(3*6)+(2*2)+(1*3)=159
159 % 10 = 9
So 139746-23-9 is a valid CAS Registry Number.

Aryl Halides as Convenient Precursors of Electrogenerated Bases. Efficient Syntheses of β-Oxo Nitriles or Esters by Coupling Active-hydrogen Groups with Esters

Barhdadi, Rachid,Gal, Jacques,Heintz, Monique,Troupel, Michel

, p. 50 - 51 (2007/10/02)

In an undivided cell fitted with a sacrificial anode and a nickel cathode on which cadmium had been deposited, the electroreduction of aromatic halides affords a strong base which allows the effective synthesis of β-oxo nitriles or β-oxo esters from the coupling of active-hydrogen compounds with esters.
