Calculate Digit Verification of CAS Registry Number 129972-84:
(8*1)+(7*2)+(6*9)+(5*9)+(4*7)+(3*2)+(2*8)+(1*4)=175
175 % 10 = 5
So 129972-84-5 is a valid CAS Registry Number.

, p. 1782 - 1786 (2007/10/02)

The title sulfide 3P=S reacted with acids to form a novel mercaptophosphonium salt X, solution thermolysis of which in the absence or presence of triphenylphosphine resulted in the unusual desulfurization to give the tertiary phosphonium salts X. (2,6)3P=S also reacted with alkyl iodides or bromides under mild conditions to give stable (alkylthio)phosphonium salts X (R=Me, Et, n-Bu), which reacted with thiols at room temperature in the presence of a catalytic amount of the tertiary phosphine (2,6)3P to give X and unsymmetrical disulfides.
