Check Digit Verification of cas no
The CAS Registry Mumber 1684-47-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,8 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1684-47:
(6*1)+(5*6)+(4*8)+(3*4)+(2*4)+(1*7)=95
95 % 10 = 5
So 1684-47-5 is a valid CAS Registry Number.

Secondary Deuterium Isotope Effect in an Electrophilic Aromatic Substitution- Protodesilylation of Trimethylphenylsilane
Szele, Ivanka
, p. 2733 - 2737 (1981)
Reaction rates for the protodesilylation of trimethylphenylsilane and of -trimethylphenylsilane by HClO4, were measured in aqueous methanol (2:5, v/v) and the secondary deuterium isotope effect for the reaction was found to be kH/kD3=0.79.The magnitude of the observed isotope effect supports a mechanism in which the rate-determining step is the proton transfer from the hydronium ion to the silane to form a ?-intermediate.
