1261085-13-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1261085-13-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,0,8 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1261085-13:
(9*1)+(8*2)+(7*6)+(6*1)+(5*0)+(4*8)+(3*5)+(2*1)+(1*3)=125
125 % 10 = 5
So 1261085-13-5 is a valid CAS Registry Number.

Photoinduced rearrangements of 3,3′-bis(arylbenzofurans)
Auzias, Mathieu,Haeussinger, Daniel,Neuburger, Markus,Wegner, Hermann A.
, p. 474 - 477 (2011)
Complex tetracyclic ring systems were assembled by a photoinduced rearrangement of 3,3′-bis(arylbenzofurans). Irradiation of 1 under N 2 atmosphere yielded the benzonaphthofurans 2 in 75-90% yield. When the reaction was conducted under an Osub
