Check Digit Verification of cas no

The CAS Registry Mumber 18243-27-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,2,4 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18243-27:
(7*1)+(6*8)+(5*2)+(4*4)+(3*3)+(2*2)+(1*7)=101
101 % 10 = 1
So 18243-27-1 is a valid CAS Registry Number.

Gas-phase ion-molecular reactions of free ethylsilylium ions with ethylene

Shchukin,Kochina,Sinotova,Ignat'ev

, p. 206 - 209 (2007/10/03)

Gas-phase reaction of ethylsilylium ions with ethylene was studied by the radiochemical method. The reaction occurs via excited adduct C4H11Si+ which structurally is a complex of ethylsilylium cation with ethylene. The lifetime of this complex is long enough for the isotope exchange between tritium atoms of the cation and a proton of ethylene, as well as the isomerization of ethylsilylium cation to dimethylsilylium to occur. Decomposition of the complex results in predominant formation of labeled ethylene.
