Check Digit Verification of cas no

The CAS Registry Mumber 880100-53-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,0,1,0 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 880100-53:
(8*8)+(7*8)+(6*0)+(5*1)+(4*0)+(3*0)+(2*5)+(1*3)=138
138 % 10 = 8
So 880100-53-8 is a valid CAS Registry Number.

Comparative study of the phospha- and arsa-Wittig reaction using 1H, 75As and 17O NMR spectroscopy

Raeck, Christian,Berger, Stefan

, p. 4934 - 4937 (2006)

The existence of oxaarsetanes during an arsa-Wittig reaction has been proved by 1H and 17O NMR spectroscopy. 75As NMR spectra were obtained from the corresponding arsonium salts and arsane oxides. The dynamic 1H NMR spectra of phospha- and arsaylides were compared. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
