54108-46-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54108-46-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,0 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 54108-46:
(7*5)+(6*4)+(5*1)+(4*0)+(3*8)+(2*4)+(1*6)=102
102 % 10 = 2
So 54108-46-2 is a valid CAS Registry Number.

Functionalization at C-5 and at the C-6 Methyl Group of 4-Methoxy-6-methyl-2-pyrone

Bacardit, R.,Moreno-Manas, M.,Pleixats, R.

, p. 157 - 160 (2007/10/02)

A new entry to C-5 substituted 4-hydroxy-6-methyl-2-pyrones has been achieved.The best conditions to prepare the monobromo and the dibromo derivatives at C-3 and the C-6 methyl group of the title pyrone have been defined.The synthetic applicability of the phosphonium salts at CH3-C-6 of both 4-methoxy-6-methyl-2-pyrone, 5, and dehydroacetic acid, 2, has also been evaluated.
