261729-76-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 261729-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,7,2 and 9 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 261729-76:
(8*2)+(7*6)+(6*1)+(5*7)+(4*2)+(3*9)+(2*7)+(1*6)=154
154 % 10 = 4
So 261729-76-4 is a valid CAS Registry Number.

Design and synthesis of novel conformationally restricted peptide secondary structure mimetics
Kim, Hwa-Ok,Nakanishi, Hiroshi,Lee, Min S.,Kahn, Michael
, p. 301 - 302 (2007/10/03)
(matrix presented) A facile synthesis of the novel conformationally restricted reverse turn mimetic is described. The key features are the preparation of the α-keto amide and tandem bicyclic ring formation.
