Check Digit Verification of cas no

The CAS Registry Mumber 945140-40-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,5,1,4 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 945140-40:
(8*9)+(7*4)+(6*5)+(5*1)+(4*4)+(3*0)+(2*4)+(1*0)=159
159 % 10 = 9
So 945140-40-9 is a valid CAS Registry Number.

Iron/tetramethylethylenediamine-catalyzed ambient-temperature coupling of alkyl grignard reagents and aryl chlorides

Rushworth, Philip J.,Hulcoop, David G.,Fox, David J.

, p. 9517 - 9521 (2013)

Tetramethylethylenediamine (TMEDA) acts as cheap and readily removed ligand in the iron-catalyzed coupling of alkyl Grignard reagents and activated aryl chlorides. The use of TMEDA allows for low ligand and iron catalyst loading as well as an increased reaction concentration and an ambient reaction temperature on a mole scale.
