73027-11-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73027-11-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,0,2 and 7 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73027-11:
(7*7)+(6*3)+(5*0)+(4*2)+(3*7)+(2*1)+(1*1)=99
99 % 10 = 9
So 73027-11-9 is a valid CAS Registry Number.

Natural Benzofuranes. Synthesis of Eupomatenoids-1, -3, -4, -5, -6, -7, and -13
McKittrick, Brian A.,Stevenson, Robert
, p. 475 - 482 (2007/10/02)
A group of eupomatenoids, natural lignans possessing 2-aryl-3-methyl-5-propenylbenzofuran structures have been synthesized by short pathways which include the intramolecular Wittig reaction of an o-bromoethylaryl benzoate ester as a key step.
