66187-15-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 66187-15-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,1,8 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 66187-15:
(7*6)+(6*6)+(5*1)+(4*8)+(3*7)+(2*1)+(1*5)=143
143 % 10 = 3
So 66187-15-3 is a valid CAS Registry Number.

Conversion of Secondary Furfuryl Alcohols and Isomaltol to Maltol and Related γ-Pyrones

Weeks, Paul D.,Brennan, Thomas M.,Brannegan, Daniel P.,Kuhla, Donald E.,Elliot, Mark L.,et al.

, p. 1109 - 1113 (2007/10/02)

A one-pot synthesis of maltol and ethylmaltol is reported.Treatment of methylfurfuryl alcohol with 2 equiv of halogen affords good yields of 4-halo-6-hydroxy-2-methyl-2H-pyran-3(6H)-ones (8), which need not be isolated and can be converted to maltol by aqueous hydrolysis in the same vessel.A similar sequence employing ethylfurfuryl alcohol yields ethylmaltol.By a related series of reactions, isomaltol (9) can be converted to maltol.
