82448-52-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82448-52-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,4,4 and 8 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82448-52:
(7*8)+(6*2)+(5*4)+(4*4)+(3*8)+(2*5)+(1*2)=140
140 % 10 = 0
So 82448-52-0 is a valid CAS Registry Number.

New Route for Synthesis of Linear Pyranoflavones
Ahluwalia, V. K.,Jain, Anjula,Prakash, Chandra,Bala, Shashi
, p. 101 - 103 (2007/10/02)
A convenient synthesis of linear pyranoflavone, viz 2,2-dimethyl-8-phenyl-2H,6H-benzodipyran-6-one(III) is described.The key steps in the synthesis of the title compounds are : (i) blocking the 8-position of appropriate 7-hydroxyflavone with
