Check Digit Verification of cas no

The CAS Registry Mumber 107716-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,7,1 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107716-49:
(8*1)+(7*0)+(6*7)+(5*7)+(4*1)+(3*6)+(2*4)+(1*9)=124
124 % 10 = 4
So 107716-49-4 is a valid CAS Registry Number.

Selectivite de la scission Si-C dans des composes du type Me3SiCH2Σ; une synthese originale et sure de l'iodoacetate d'ethyle

Bordeau, M.,Djamei, S. M.,Dunogues, J.

, p. 413 - 417 (2007/10/02)

The regiochemistry of the electrophilic cleavage of the SiCsp3 bond in compounds Me3SiCH2Σ (Σ = Me, Pr, Cl, COOEt) and Me3SiCHΣ2 (Σ = Cl) has been investigated using ICl, Me3SiOSO2Cl and HO3SCl as the electrophiles.When Σ = Pr or Cl a regioselective cleavage of the Si-CH3 bond was observed, producing silylated chlorosulfonates or sulfates which often were new compounds.With Σ = COOEt a regiospecific splitting of the Si-CH2COOEt bond was observed.This confirms the synthetic potential of ethyl trimethylsilylacetate.
