22997-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 22997-64-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,9 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 22997-64:
(7*2)+(6*2)+(5*9)+(4*9)+(3*7)+(2*6)+(1*4)=144
144 % 10 = 4
So 22997-64-4 is a valid CAS Registry Number.

Configurationally stable propeller-like triarylphosphine and triarylphosphine oxide

Pinter, Aron,Haberhauer, Gebhard,Hyla-Kryspin, Isabella,Grimme, Stefan

, p. 3711 - 3713 (2007)

Configurationally stable, propeller-like triarylphosphine and triarylphosphine oxide can be synthesized; a chiral scaffold based on Lissoclinum-cyclopeptides linked via three peptide bonds with a triphenylphosphine and triphenylphosphine oxide moiety, respectively, prevents effectively epimerization at the chiral phosphorus atom.

A new synthesis of hydrophilic carboxylated arylphosphines

Ravindar,Hemling,Schumann,Blum

, p. 841 - 851 (2007/10/02)

An efficient synthetic procedure for the preparation of versatile functionally substituted arylphosphines from commercially available starting materials is reported together with alternative routes for (carboxyphenyl)diphenyl phosphines.
