944059-75-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 944059-75-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,0,5 and 9 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 944059-75:
(8*9)+(7*4)+(6*4)+(5*0)+(4*5)+(3*9)+(2*7)+(1*5)=190
190 % 10 = 0
So 944059-75-0 is a valid CAS Registry Number.

C-C bond formation by radical cyclization: Regioselective synthesis of [6,6] pyrano pyran system
Majumdar,Jana
, p. 1735 - 1745 (2008/02/01)
A number of 4-aryloxymethyl pyrano[3,2-c][1]benzopyran-5-(2H)-ones 3(a-f) were prepared by refluxing 4-chloromethyl pyrano[3,2-c][1]benzopyran-5-(2H)-ones 1(a,b) with o-bromophenols 2(a-c) in acetone in the presence of anhydrous potassium carbonate and so
