138846-94-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138846-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,4 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138846-94:
(8*1)+(7*3)+(6*8)+(5*8)+(4*4)+(3*6)+(2*9)+(1*4)=173
173 % 10 = 3
So 138846-94-3 is a valid CAS Registry Number.

Benzodiazepine Analogues. Part 11.1 a Kinetic-Mechanistic Study of the Formation of 1,5-Benzodioxepin-2-ones via Baeyer-Villiger Oxidation of Flavanones

Gelebe, Aifheli C.,Kaye, Perry T.

, p. 26 - 27 (2007/10/03)

The regioselective Baeyer-Villiger rearrangement of selected flavanones to 1,5-benzodioxepin-2-ones, using m-chloroperbenzoic acid in CD2Cl2, has been monitored by 1H NMR spectroscopy: substituent effects on the magnitude of the second-order rate constant and the regioselectivity of heteroatom insertion have been examined.

Synthesis and structure of 3,4-dihydro-4-phenyl-1,5-benzodioxepin-2-ones

Gelebe,Kaye,Lidell

, p. 2263 - 2268 (2007/10/02)

Baeyer-Villiger rearrangement of substituted flavanones using MCPBA affords ring-expanded products, shown by NMR spectroscopy to be the corresponding 3,4-dihydro-4-phenyl-1,5-benzodioxepin-2-ones.
