Check Digit Verification of cas no
The CAS Registry Mumber 7242-59-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,4 and 2 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7242-59:
(6*7)+(5*2)+(4*4)+(3*2)+(2*5)+(1*9)=93
93 % 10 = 3
So 7242-59-3 is a valid CAS Registry Number.

Phosphadioxirane Intermediates in the Reaction of Singlet Oxygen with Phosphites and Phosphines
Tsuji, Shoei,Kondo, Masaaki,Ishiguro, Katsuya,Sawaki, Yasuhiko
, p. 5055 - 5059 (2007/10/02)
Intermediates in the singlet oxygen reaction of phosphites and phosphines have been studied by trapping and tracer experiments.Trapping study with diphenyl sulfoxide revealed that the added substrate and phosphite are competing toward the same intermediate.The relative reactivity of (BuO)3P/Ph2S/Ph2SO = 300:4:1 and the negative ρ-value of -0.63 for diphenyl sulfoxides are not consistent with 1,3-dipolar phosphine peroxides, but suggest electrophilic O-transfers by cyclic phosphadioxiranes.Intermediacy of phosphadioxiranes was supported by an 18O-tracer study on the formation of rearranged diphenylphosphinate from 1O2 and triphenylphosphine.Theoretical calculations also supported the dioxirane intermediate by predicting no existence of 1,3-dipolar peroxide.
