2783-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2783-12-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,8 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2783-12:
(6*2)+(5*7)+(4*8)+(3*3)+(2*1)+(1*2)=92
92 % 10 = 2
So 2783-12-2 is a valid CAS Registry Number.

One-pot asymmetric conjugate addition-trapping of zinc enolates by activated electrophiles
Rathgeb, Xavier,March, Sebastien,Alexakis, Alexandre
, p. 5737 - 5742 (2007/10/03)
The copper-catalyzed asymmetric conjugate addition of dialkyl zinc leads to homochiral zinc enolates. These intermediates were trapped in situ with activated allylic electrophiles, without the need of additional palladium catalysis. High trans selectivity
