Calculate Digit Verification of CAS Registry Number 138696-27:
(8*1)+(7*3)+(6*8)+(5*6)+(4*9)+(3*6)+(2*2)+(1*7)=172
172 % 10 = 2
So 138696-27-2 is a valid CAS Registry Number.

Oxidations of Thiourethanes, 10.- Synthesis, Crystal Structures, Oxidation and Photochemistry of Thione S-Oxides of Cyclic Dithiourethanes and Dithiocarbazates

Hanefeld, Wolfgang,Schlitzer, Martin,Schuetz, Harald,Wocadlo, Sigrid,Massa, Werner

, p. 337 - 344 (2007/10/02)

Several cyclic dithiocarbamates and dithiocarbazates (2-4) have been oxidised with mCPBA to give the correspnding thione S-oxides 5-7.The sulfine structure was confirmed by oxidation to the corresponding oxo derivatives and X-ray crystal structures analys
