498538-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 498538-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,8,5,3 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 498538-67:
(8*4)+(7*9)+(6*8)+(5*5)+(4*3)+(3*8)+(2*6)+(1*7)=223
223 % 10 = 3
So 498538-67-3 is a valid CAS Registry Number.

Synthesis, spectroscopic characterization and chemical reactions of stable o-QM on solid phase
Zanaletti, Riccardo,Freccero, Mauro
, p. 1908 - 1909 (2002)
A novel approach towards quinone methides stabilization has been achieved by anchoring the reactive o-QM intermediate on solid phase (RTHP). The reactivity and selectivity of supported o-QM towards N and S centered nucleophiles have been explored.
