Check Digit Verification of cas no

The CAS Registry Mumber 4515-52-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,1 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 4515-52:
(6*4)+(5*5)+(4*1)+(3*5)+(2*5)+(1*2)=80
80 % 10 = 0
So 4515-52-0 is a valid CAS Registry Number.

Synthesis of bifunctional disiloxanes: Via subsequent hydrosilylation of alkenes and alkynes

Szyling, Jakub,Januszewski, Rafa?,Jankowska, Kamila,Walkowiak, J?drzej,Kownacki, Ireneusz,Franczyk, Adrian

supporting information, p. 4504 - 4507 (2021/05/17)

The first protocol for the synthesis of unsymmetrical bifunctional 1,1,3,3-tetramethyldisiloxane derivatives via subsequent hydrosilylation of alkenes and alkynes is presented. The methodology described has vast functional group tolerance and is extremely efficient towards the formation of novel disiloxane-based building blocks.

29Si and 13C NMR Spectra of 4-Substituted 2-Methoxytrimethylsiloxybenzenes. Factors Determining the Chemical Shifts in Models of Lignin Constituents

Schraml, Jan,Kvicalova, Magdalena,Chvalovsky, Vaclav,Elder, Thomas,Brezny, Robert

, p. 973 - 978 (2007/10/02)

29Si and 13C NMR chemical shifts are reported for a series of twenty 4-substituted 2-methoxytrimethylsiloxybenzenes; the set of substituents incorporates a basic set of ten substituents differing in their relative polar and resonance effects and ten other
