66393-56-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66393-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,9 and 3 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66393-56:
(7*6)+(6*6)+(5*3)+(4*9)+(3*3)+(2*5)+(1*6)=154
154 % 10 = 4
So 66393-56-4 is a valid CAS Registry Number.

Synthesis and applications to asymmetric catalysis of a series of mono- and bis(diazaphospholidine) ligands

Smyth,Tye,Eldred,Alcocka,Wills

, p. 2840 - 2849 (2007/10/03)

The synthesis of a series of closely related mono- and bis(diazaphospholidine) ligands has been achieved using the condensation of a diamine with a bis(dimethylamino)arylphosphine. The resulting ligands have given excellent results in palladium-catalysed allylic substitution reactions to form C-C bonds (up to 89% ee) and C-N bonds (up to 78% ee).
