Check Digit Verification of cas no

The CAS Registry Mumber 1152491-52-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,2,4,9 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1152491-52:
(9*1)+(8*1)+(7*5)+(6*2)+(5*4)+(4*9)+(3*1)+(2*5)+(1*2)=135
135 % 10 = 5
So 1152491-52-5 is a valid CAS Registry Number.

Silylene and germylene intermediates in the reactions of silole and germole dianions with N,N′-Di-tert-butylethylenediimine

Toulokhonova, Irina S.,Timokhin, Vitaly I.,Bunck, David N.,Guzei, Ilia,West, Robert,Mueller, Thomas

, p. 2344 - 2349 (2008)

Spiro-diazasilole (germole) adducts were observed in reactions of dilithium salts of silole and germole dianions with N,N′-di-tert- butylethylenediimine in THF at room temperature. A proposed mechanism of the reaction includes metallation of N,N′-di-tert-butylethylenediimine and the formation of an intermediate silylene or germylene. This reaction mechanism was supported by experimental data and theoretical calculations. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
