Check Digit Verification of cas no

The CAS Registry Mumber 39997-45-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,9,9 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 39997-45:
(7*3)+(6*9)+(5*9)+(4*9)+(3*7)+(2*4)+(1*5)=190
190 % 10 = 0
So 39997-45-0 is a valid CAS Registry Number.

Preparation and -Cycloaddition of Methylthio-chlorophosphanes RP(Cl)SMe (R = Me, Et, Ph)

Apitz, Joerg,Grobe, Joseph,Le Van, Duc

, p. 257 - 260 (2007/10/02)

The methylthio-chlorophosphanes RP(Cl)SMe are prepared in good yields (62-65percent) by condensation reactions of the corresponding dichlorophosphanes RPCl2 with methanethiol in the presence of trimethylamine (molar ratio 1:1:1). 1 and 3 have been used to produce 3-phospholene sulfides in a one-pot process by reaction with 1,3-dienes at 70 to 100 deg C.Reaction proceeds via -cycloadducts, which in suitable cases can be isolated and used for the preparation of the corresponding 3-phospholene oxides.New compounds were characterized by elemental analysis and spectroscopic investigations (NMR, MS). - Keywords: Methylthio-chlorophosphanes, 3-Phospholene Sulfides and Oxides, Mass Spectra, NMR Spectra
