Check Digit Verification of cas no

The CAS Registry Mumber 1226783-80-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,6,7,8 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1226783-80:
(9*1)+(8*2)+(7*2)+(6*6)+(5*7)+(4*8)+(3*3)+(2*8)+(1*0)=167
167 % 10 = 7
So 1226783-80-7 is a valid CAS Registry Number.

Gold-catalyzed intramolecular indole/alkyne cyclization cascades through a heterolytic fragmentation: 1,5-indole migration and allenylation

Li, Guijie,Liu, Yuanhong

supporting information; experimental part, p. 3526 - 3528 (2010/08/03)

Gold-catalyzed intramolecular reactions of 3-alkynyl-bearing indoles with diol groups lead to the formation of highly functionalized 3-allenylindoles with high efficiency. The reaction likely proceeds by a new gold-catalyzed cascade cyclization/heterolytic fragmentation/elimination reactions, which results in 1,5-indole migration and C-3 allenylation of indole moiety.
