Check Digit Verification of cas no

The CAS Registry Mumber 21983-00-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,8 and 3 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 21983-00:
(7*2)+(6*1)+(5*9)+(4*8)+(3*3)+(2*0)+(1*0)=106
106 % 10 = 6
So 21983-00-6 is a valid CAS Registry Number.

PROCESS FOR PREPARING BORONIC ACIDS AND ESTERS IN THE PRESENCE OF MAGNESIUM METAL

-

Page/Page column 9-10, (2011/11/30)

The present invention relates to the process for preparing a boronic acid or ester chemically, in which an aromatic compound is reacted with a boronating agent, in the presence of magnesium metal (Mg0). The invention also relates to the boronic acids or esters that can be obtained by means of this process and to the use thereof for example as a synthesis intermediate, in the Suzuki reaction, in the pharmaceutical or alternatively electronics field.

Electrosynthesis of benzylboronic acids and esters

Pintaric,Laza,Olivero,Du?ach

, p. 8031 - 8033 (2007/10/03)

A novel preparation of benzylboronic acids and esters is described by using an electrochemical reductive coupling reaction between benzylic halides and borating agents (trialkylborates or pinacolborane). The reaction is carried out at room temperature in DMF or THF with the use of a sacrificial magnesium anode in a single-compartment cell.
