144809-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144809-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,8,0 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 144809-40:
(8*1)+(7*4)+(6*4)+(5*8)+(4*0)+(3*9)+(2*4)+(1*0)=135
135 % 10 = 5
So 144809-40-5 is a valid CAS Registry Number.

Copper-catalyzed allylic alkylations of alkylzirconium intermediates
Venanzi, Luigi M.,Lehmann, Roman,Keil, Robert,Lipshutz, Bruce H.
, p. 5857 - 5860 (2007/10/02)
Hydrozirconation of olefins followed by exposure of the resulting alkylzirconium species to catalytic CuCN in the presence of activated halides or phosphonates gives rise to products of aklkylation in good yields under mild conditions.
