2921-67-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2921-67-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2921-67:
(6*2)+(5*9)+(4*2)+(3*1)+(2*6)+(1*7)=87
87 % 10 = 7
So 2921-67-7 is a valid CAS Registry Number.

Direct esterification of phosphinic acids under microwave conditions: Extension to the synthesis of thiophosphinates and new mechanistic insights

Keglevich, Gy?rgy,Kiss, Nóra Zsuzsa,Drahos, László,K?rtvélyesi, Tamás

, p. 466 - 469 (2013)

The direct esterification of phosphinic acids has been extended to the preparation of thiophosphinates using thiols, but the conversions are only ca. 50%. The outcome is in agreement with the unexpectedly high enthalpy of activation and endothermicity sug
