130482-94-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130482-94-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,4,8 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130482-94:
(8*1)+(7*3)+(6*0)+(5*4)+(4*8)+(3*2)+(2*9)+(1*4)=109
109 % 10 = 9
So 130482-94-9 is a valid CAS Registry Number.

Oxidations with 2,3-dichloro-5-, 6-dicyano-p-benzoquinone (DDQ): Part III - Oxidation of spironaphthalenols - Synthesis of naphtho[2, 1-b]furan derivatives
Kasturi,Jayaram,Mathew
, p. 628 - 631 (2007/10/02)
Oxidation of the spironaphthalenols (3a-c and 4) with DDQ gives the naphtho[2, 2-b]furan derivatives (5a-c and 6a-c). The spectral properties (IR and NMR) of these compounds are discussed.
