Check Digit Verification of cas no

The CAS Registry Mumber 203940-76-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,9,4 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 203940-76:
(8*2)+(7*0)+(6*3)+(5*9)+(4*4)+(3*0)+(2*7)+(1*6)=115
115 % 10 = 5
So 203940-76-5 is a valid CAS Registry Number.

Isomerization of 4-aminobenzofurans to 4-hydroxyindoles

Chilin,Rodighiero,Guiotto

, p. 309 - 312 (1998)

4-Amino-2-methylbenzofurans are quantitatively converted to 4-hydroxy- 2-methylindoles in acidic medium. The rearrangement mechanism involves the ring opening of the furan ring to produce an intermediate carbocation, which undergoes ring clo- sure to the
