The CAS Registry Mumber 1228932-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,9,3 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1228932-17:
(9*1)+(8*2)+(7*2)+(6*8)+(5*9)+(4*3)+(3*2)+(2*1)+(1*7)=159
159 % 10 = 9

3,5-Disubstituted 6H-pyrrolo[1,2-c][1,2,3]triazoles from Morita-Baylis-Hillman adducts of propargyl aldehydes

Park, Sun Pil,Ahn, Sang-Hyun,Lee, Kee-Jung

experimental part, p. 3490 - 3498 (2010/06/17)

A simple method for synthesizing several 6H-pyrrolo[1,2-c][1,2,3]triazole derivatives having a methoxycarbonyl or an acetyl group at C-5 position and 7,8-dihydro-4H-[1,2,3]triazolo[1,5-a]indol-5(6H)-ones via an intramolecular 1,3-dipolar cycloaddition reaction of azido enynes, which were readily obtained from the Morita-Baylis-Hillman acetates of propargyl aldehydes with sodium azide, has been developed.
