20056-42-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20056-42-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,0,5 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20056-42:
(7*2)+(6*0)+(5*0)+(4*5)+(3*6)+(2*4)+(1*2)=62
62 % 10 = 2
So 20056-42-2 is a valid CAS Registry Number.

Markowska, A.,Olejnik, J.,Mlotkowska, B.,Sobanska, M.
, p. 143 - 146 (2007/10/02)
Arylation of diethyl phosphoric acid by triphenylphosphite leading to diethylphenylphosphate was studied by NMR-spectroscopy.The mixed PIII-PIV-anhydride was proved to be an intermediate.The scope of arylation is presented.
