118049-75-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 118049-75-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,4 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 118049-75:
(8*1)+(7*1)+(6*8)+(5*0)+(4*4)+(3*9)+(2*7)+(1*5)=125
125 % 10 = 5
So 118049-75-5 is a valid CAS Registry Number.

A convenient microwave-assisted propylphosphonic anhydride (T3P mediated one-pot pyrazolone synthesis

Desroses, Matthieu,Jacques-Cordonnier, Marie-Caroline,Llona-Minguez, Sabin,Jacques, Sylvain,Koolmeister, Tobias,Helleday, Thomas,Scobie, Martin

supporting information, p. 5879 - 5885 (2013/09/23)

This paper describes a facile, efficient, and clean synthesis of various pyrazolones by employing T3P as a catalyst and performing the reaction under microwave irradiation. This two-step, one-pot reaction proceeded readily and tolerated a variety of functional groups. A wide range of pyrazolone derivatives were obtained in good to excellent yields. A one-pot, two-step procedure for the synthesis of pyrazolones is presented. This method, which uses T3P and microwave irradiation, is particularly easy to carry out and offers a notable alternative to the strongly acidic conditions that are generally employed with other synthetic approaches.
