Calculate Digit Verification of CAS Registry Number 191227-59:
(8*1)+(7*9)+(6*1)+(5*2)+(4*2)+(3*7)+(2*5)+(1*9)=135
135 % 10 = 5
So 191227-59-5 is a valid CAS Registry Number.

The cathodic cleavage of the S-P bond. Synthesis and electrochemical behaviour of sulfonamide phosphorus analogues

Pilard, Jean-Francois,Simonet, Jacques

, p. 3735 - 3738 (1997)

P-diphenylarylsulfophosphamides can be obtained by condensation of Ph2PLi on various arylsulfonyl chlorides. These sulfonamide phosphorus analogues exhibit facile cathodic cleavage reaction yielding, after quenching, diphenylphosphinic acid and arylsulfide.
