3917-24-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3917-24-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,1 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3917-24:
(6*3)+(5*9)+(4*1)+(3*7)+(2*2)+(1*4)=96
96 % 10 = 6
So 3917-24-6 is a valid CAS Registry Number.

Catalytic asymmetric intramolecular hydroacylation with rhodium/phosphoramidite-alkene ligand complexes

Hoffman, Thomas J.,Carreira, Erick M.

supporting information; experimental part, p. 10670 - 10674 (2011/12/05)

Give me a P: An asymmetric intramolecular Rh-catalyzed hydroacylation reaction of pent-4-enals for the preparation of functionalized cyclopentanones in good yield and high enantioselectivity is described (see scheme, DCE=dichloroethane). This process uses rhodium complexes featuring novel modular phosphoramidite-alkene ligands and achiral phosphine coligands. Copyright
