Check Digit Verification of cas no

The CAS Registry Mumber 1410747-77-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,1,0,7,4 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1410747-77:
(9*1)+(8*4)+(7*1)+(6*0)+(5*7)+(4*4)+(3*7)+(2*7)+(1*7)=141
141 % 10 = 1
So 1410747-77-1 is a valid CAS Registry Number.

Lewis-acid-mediated ring-exchange reaction of dihydrobenzofurans and its application to the formal total synthesis of (-)-quinocarcinamide

Chiba, Hiroaki,Sakai, Yuki,Oishi, Shinya,Fujii, Nobutaka,Ohno, Hiroaki

, p. 6273 - 6276,4 (2012/12/12)

An unusual Lewis-acid-mediated ring-exchange reaction of dihydrobenzofurans is described. The fused tricyclic ring system is the key structural element for this reaction as it restricts C-N bond rotation and/or destabilizes the benzofuran ring. We achieved the formal total synthesis of (-)-quinocarcinamide using a combination of this reaction and the Au(I)-catalyzed 6-endo-dig hydroamination of an alkyne.
