84346-78-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84346-78-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,3,4 and 6 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84346-78:
(7*8)+(6*4)+(5*3)+(4*4)+(3*6)+(2*7)+(1*8)=151
151 % 10 = 1
So 84346-78-1 is a valid CAS Registry Number.

A NEW SYNTHESIS OF 4-CHROMANONES
Primo, Jaime,Tormo, Rosa,Miranda, Miquel A.
, p. 1819 - 1822 (2007/10/02)
Aryl esters of α,β-unsaturated carboxylic acids undergo photorearrangement, followed by basic cyclization, to give 4-chromanones.Reduction dehydration of these compounds affords 2H-chromenes in excellent overall yields.
