54844-85-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54844-85-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,8,4 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 54844-85:
(7*5)+(6*4)+(5*8)+(4*4)+(3*4)+(2*8)+(1*5)=148
148 % 10 = 8
So 54844-85-8 is a valid CAS Registry Number.

A new palladium-catalyzed P-C coupling reaction: Synthesis of triarylphosphine oxides and diarylmethylphosphine oxides

Stark, Gene A.,Riermeier, Thomas H.,Beller, Matthias

, p. 1703 - 1711 (2000)

The first palladium-catalyzed P-C coupling reaction of aryl halides with (hydroxymethyl)phosphines is described. Hydroxymethylphosphines act as cheap and easy to use H3PO and CH3P(O)H2 equivalents. Tertiary diarylmethylphosphine oxides 5 and triarylphosphine oxides 6 are accessible in a one pot reaction in overall yields between 45-60%.
