Check Digit Verification of cas no
The CAS Registry Mumber 138983-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,8 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 138983-68:
(8*1)+(7*3)+(6*8)+(5*9)+(4*8)+(3*3)+(2*6)+(1*8)=183
183 % 10 = 3
So 138983-68-3 is a valid CAS Registry Number.

Novel synthesis of arylboronic acids by electroreduction of aromatic halides in the presence of trialkyl borates
Laza, Carine,Dunach, Elisabet,Serein-Spirau, Francoise,Moreau, Joel J. E.,Vellutini, Luc
, p. 373 - 375 (2002)
A novel preparation of aryl and heteroarylboronic acids by an electrochemical coupling reaction is described. It is based on the reductive coupling between aromatic or heteroaromatic halides and a trialkyl borate. The reactions are carried out in DMF or THF with the use of sacrificial aluminium or magnesium anodes in a single-compartment cell. Arylboronic acids are obtained with moderate to good selectivities and isolated yields.
