Check Digit Verification of cas no
The CAS Registry Mumber 137605-07-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,0 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 137605-07:
(8*1)+(7*3)+(6*7)+(5*6)+(4*0)+(3*5)+(2*0)+(1*7)=123
123 % 10 = 3
So 137605-07-3 is a valid CAS Registry Number.

Anodic oxidation of 2,3-diarylbenzofurans : Different reaction pathways for the cation radical
Cariou, Michel,Simonet, Jacques
, p. 4913 - 4916 (2007/10/02)
The electrooxidation of 2,3-diarylbenzofurans leads to a rearrangement lactone, 3,3-diaryl-2(3H)-benzofuranone, together with a ring enlargement product, 9-aroyl-9-hydroxy-(9H)-xanthene. However, in some cases coupling products may be isolated in high yie
