Check Digit Verification of cas no
The CAS Registry Mumber 1449115-43-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,9,1,1 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1449115-43:
(9*1)+(8*4)+(7*4)+(6*9)+(5*1)+(4*1)+(3*5)+(2*4)+(1*3)=158
158 % 10 = 8
So 1449115-43-8 is a valid CAS Registry Number.

Conversion of cyclic ketones to 2,3-fused pyrroles and substituted indoles
Alford, Joshua S.,Spangler, Jillian E.,Davies, Huw M.L.
, p. 11712 - 11715 (2013/09/02)
A highly effective synthesis of 2,3-fused pyrroles from cyclic ketones has been achieved. The transformation includes a rhodium-catalyzed reaction of 4-alkenyl-1-sulfonyl-1,2,3-triazoles featuring an unusual 4π electrocyclization. The methodology was furt
