18771-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 18771-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,7 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 18771-58:
(7*1)+(6*8)+(5*7)+(4*7)+(3*1)+(2*5)+(1*8)=139
139 % 10 = 9
So 18771-58-9 is a valid CAS Registry Number.

THE MECHANISM OF CLEAVAGE OF Si-Ge BONDS BY BASE
Eaborn, Colin,Mahmoud, Foad M.S.
, p. 47 - 51 (2007/10/02)
The compounds R3SiGePh3 with R = Me or Et have been shown to undergo cleavage in NaOMe-MeOH to give Ph3GeH.From rate measurements and solvent isotope effect studies it is concluded that the Ph3Ge- anion separates in the rate-determining transit
