Check Digit Verification of cas no

The CAS Registry Mumber 72059-93-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,5 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 72059-93:
(7*7)+(6*2)+(5*0)+(4*5)+(3*9)+(2*9)+(1*3)=129
129 % 10 = 9
So 72059-93-9 is a valid CAS Registry Number.

The Permethylcyclosilanes (Me2Si)5 through (Me2Si)35

Brough, Lawrence F.,West, Robert

, p. 3049 - 3056 (2007/10/02)

The cyclic permethylpolysilanes (Me2Si)n, where n = 5-35, are all formed when dimethyldichlorosilane (Me2SiCl2) is added slowly to sodium-potassium (Na/K) alloy in tetrahydrofuran (THF).NMR, UV, and vibrational spectra are reported for compounds n = 5-19.The 13C NMR and 1H NMR spectra are explained in terms of methyl-methyl group interactions.Raman and IR spectra are assigned and partially explained on the basis of a standing wave model.
