847267-71-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 847267-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,7,2,6 and 7 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 847267-71:
(8*8)+(7*4)+(6*7)+(5*2)+(4*6)+(3*7)+(2*7)+(1*1)=204
204 % 10 = 4
So 847267-71-4 is a valid CAS Registry Number.

Synthesis and electrochemistry of meso-substitutes dipyrromethene nickel (II) complexes

Wang, Yemei,Xue, Zhaoli,Dong, Yuan,Zhu, Weihua

, p. 578 - 582 (2015)

Metalation of dipyrromethene (dipyrrin) (1a-c) with Ni(OAc)2 provides Ni-dipyrrole complexes (NiL2) (2a-c) in 37-47% yields. The complexes were characterized by mass spectrometry and UV-Vis absorption, 1H NMR spectroscopy

Preparation of α,β-unsubstituted meso-arylbidipyrrins via metal-templated, oxidative coupling of dipyrrins

Gill, Hubert S.,Finger, Isaac,Bozidarevic, Ivana,Szydlo, Florence,Scott, Michael J.

, p. 68 - 71 (2007/10/03)

A three-step, one-pot procedure provides meso-aryl-α,β- unsubstituted bisdipyrrinato nickel complexes; oxidative coupling of these ligands followed by demetallation affords an unprecedented class of meso-aryl-α,β-unsubstituted bidipyrrins.
