2169-20-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2169-20-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,6 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2169-20:
(6*2)+(5*1)+(4*6)+(3*9)+(2*2)+(1*0)=72
72 % 10 = 2
So 2169-20-2 is a valid CAS Registry Number.

One-Pot Synthesis of Butadiyne-Bridged Bipyrrole Derivatives and Bisporphyrin

Kishore, M. V. Nanda,Panda, Pradeepta K.

, p. 5197 - 5203 (2017)

Butadiyne-bridged bipyrroles were prepared from 2-iodopyrroles and trimethylsilylacetylene through a facile one-pot synthesis involving a modified Sonogashira coupling reaction and in situ aerobic oxidative coupling of the acetylenic pyrroles; the products were obtained in yields of 31–72 % depending on the substituents on the pyrrole. The acetylene-bridged diacids obtained from the hydrolysis of the corresponding ester derivatives are highly stable, unlike most reported oligopyrrolic diacids. This protocol could be easily extended towards the synthesis of butadiyne-bridged bisporphyrins.
