405-84-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 405-84-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 405-84:
(5*4)+(4*0)+(3*5)+(2*8)+(1*4)=55
55 % 10 = 5
So 405-84-5 is a valid CAS Registry Number.

Palladium-catalyzed, asymmetric Mizoroki-Heck reaction of benzylic electrophiles using phosphoramidites as chiral ligands

Yang, Zhigang,Zhou, Jianrong

supporting information; experimental part, p. 11833 - 11835 (2012/09/08)

We report herein the first examples of asymmetric Mizoroki-Heck reactions using benzyl electrophiles. A new phosphoramidite was identified to be an effective chiral ligand in the palladium-catalyzed reaction. The reaction is compatible with polar functional groups and can be readily scaled up. Several cyclic olefins worked well as olefin components. Thirty-one examples are included.
