283173-76-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 283173-76-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,3,1,7 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 283173-76:
(8*2)+(7*8)+(6*3)+(5*1)+(4*7)+(3*3)+(2*7)+(1*6)=152
152 % 10 = 2
So 283173-76-2 is a valid CAS Registry Number.

Pd-catalyzed cascade cyclization by intramolecular heck insertion of an allene-allylic amination sequence: Application to the synthesis of 3,4-fused tricyclic indoles

Nakano, Shun-Ichi,Inoue, Naoya,Hamada, Yasumasa,Nemoto, Tetsuhiro

, p. 2622 - 2625 (2015)

A novel Pd-catalyzed cascade cyclization by intramolecular Heck insertion of an allene-allylic amination sequence was developed. Allenes tethered to ortho-iodoaniline derivatives at the meta-position were reacted with 5-10 mol % of Pd catalyst and 4 equiv

Diphenylacetylene-linked peptide strands induce bidirectional β-sheet formation

Lingard, Hannah,Han, Jeongmin T.,Thompson, Amber L.,Leung, Ivanhoe K. H.,Scott, Richard T. W.,Thompson, Sam,Hamilton, Andrew D.

supporting information, p. 3650 - 3653 (2014/04/17)

In the search for synthetic mimics of protein secondary structures relevant to the mediation of protein-protein interactions, we have synthesized a series of tetrasubstituted diphenylacetylenes that display β-sheet structures in two directions. Extensive
