Check Digit Verification of cas no

The CAS Registry Mumber 34868-20-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,6 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 34868-20:
(7*3)+(6*4)+(5*8)+(4*6)+(3*8)+(2*2)+(1*0)=137
137 % 10 = 7
So 34868-20-7 is a valid CAS Registry Number.

Evidence of Phosphonium-Carbenium Dication Formation in a Superacid: Precursor to Fluorinated Phosphine Oxides

Castelli, Ugo,Lohier, Jean-Fran?ois,Drukenmüller, Ines,Mingot, Agnès,Bachman, Christian,Alayrac, Carole,Marrot, Jér?me,Stierstorfer, Karin,Kornath, Andreas,Gaumont, Annie-Claude,Thibaudeau, Sébastien

Unambiguously confirmed by low-temperature in situ NMR experiments, X-ray diffraction and vibrational spectroscopy, phosphonium-carbenium superelectrophiles are shown to be generated in strong acidic conditions. Representing crucial intermediates, their exploitation allows for the synthesis of unprecedented fluorinated (cyclic) phosphine oxides.
