Check Digit Verification of cas no
The CAS Registry Mumber 120028-43-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,0,2 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 120028-43:
(8*1)+(7*2)+(6*0)+(5*0)+(4*2)+(3*8)+(2*4)+(1*3)=65
65 % 10 = 5
So 120028-43-5 is a valid CAS Registry Number.

New total synthesis of O-methyledgeworin and edgeworin
Kirkiacharian, B. Serge,Brillard, Marie
, p. 541 - 546 (2006)
Upon thermal condensation of diethyl (coumarinyl-7-oxy)malonate with O-methyl-resorcine, the corresponding bis[coumarinyl]ether, 4-hydroxy-O-methyl- edgeworin is obtained in good yield. This leads to 4-bromo-O-methyledgeworin, O-methyledgeworin, and edgeworin. Copyright Taylor & Francis Group, LLC.
