21645-07-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21645-07-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,4 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21645-07:
(7*2)+(6*1)+(5*6)+(4*4)+(3*5)+(2*0)+(1*7)=88
88 % 10 = 8
So 21645-07-8 is a valid CAS Registry Number.

A concise method for synthesis of diaryl aryl- or alkylphosphonates

Yao, Qiang,Levchik, Sergei

, p. 277 - 281 (2007/10/03)

A convenient method has been developed to synthesize diaryl arylphosphonates from triaryl phosphites, triethyl phosphite, and aromatic halides. The new method relies on the triethyl phosphite assisted nickel catalyzed Arbuzov reaction and can be applied to synthesize certain diaryl alkylphosphonates without catalysts.

Mild and efficient Cs2CO3-promoted synthesis of phosphonates

Cohen, Richard J.,Fox, Daniel L.,Eubank, Jarrod F.,Salvatore, Ralph Nicholas

, p. 8617 - 8621 (2007/10/03)

A mild and convenient synthesis for phosphonates using cesium carbonate (Cs2CO3), tetrabutylammonium iodide (TBAI) and DMF was developed at room temperature. Numerous dialkyl phosphites were screened using a diverse array of alkyl halides and these reaction conditions were found to be highly efficient producing various phosphonates exclusively in moderate to high yields.
