122593-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 122593-71-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,5,9 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 122593-71:
(8*1)+(7*2)+(6*2)+(5*5)+(4*9)+(3*3)+(2*7)+(1*1)=119
119 % 10 = 9
So 122593-71-9 is a valid CAS Registry Number.

A CONVENIENT PREPARATION OF α-PHOSPHONO ESTERS AND LACTONES VIA C-P BOND FORMATION
Lee, Koo,Wiemer, David F.
, p. 87 - 90 (2007/10/02)
The reaction of ester and lactone enolates with diethyl phosphorochloridite, followed by air oxidation of the immediate reaction products, has proven to be a general alternative to the traditional Arbuzov synthesis of α-phosphono esters and lactones.
