92505-48-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 92505-48-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,5,0 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 92505-48:
(7*9)+(6*2)+(5*5)+(4*0)+(3*5)+(2*4)+(1*8)=131
131 % 10 = 1
So 92505-48-1 is a valid CAS Registry Number.

Synthesis of tetra- and pentasubstituted benzenes from dimedone and derivatives
Nelson,Nelson
, p. 1287 - 1290 (2007/10/02)
Treatment of dimedone (5,5-dimethylcyclohexane-1,3-dione) and derivatives with one molar equivalent of sulfuric acid in trifluoroacetic anhydride leads, via sulfonation and a 1,2-methyl group migration, to a variety of dimethylresorcinol derivatives. The
