106543-49-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 106543-49-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,5,4 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 106543-49:
(8*1)+(7*0)+(6*6)+(5*5)+(4*4)+(3*3)+(2*4)+(1*9)=111
111 % 10 = 1
So 106543-49-1 is a valid CAS Registry Number.

, p. 357 - 360 (2007/10/02)
By regioselective self-coupling with silver oxide as oxidant the 2,3-trans-2-phenylbenzofuran 8 was synthesized in good yield.Reduction of 8 led in an unambiguous way to americanin-D (rac-1).Synthetic and natural product were identical in every respect.
