871117-33-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871117-33-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,1,1 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 871117-33:
(8*8)+(7*7)+(6*1)+(5*1)+(4*1)+(3*7)+(2*3)+(1*3)=158
158 % 10 = 8
So 871117-33-8 is a valid CAS Registry Number.

Ring closure to β-turn mimics via copper-catalyzed azide/alkyne cycloadditions
Angell, Yu,Burgess, Kevin
, p. 9595 - 9598 (2007/10/03)
Copper-catalyzed azide alkyne cycloadditions of the linear substrates 1 were used to form the cyclic derivatives 2. Computational, NMR, and CD analyses of these compounds indicate that their most favorable conformational states include type I and type II
