Check Digit Verification of cas no

The CAS Registry Mumber 251449-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,4,4 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 251449-99:
(8*2)+(7*5)+(6*1)+(5*4)+(4*4)+(3*9)+(2*9)+(1*9)=147
147 % 10 = 7
So 251449-99-7 is a valid CAS Registry Number.

Synthesis of C1- and C 3ν-symmetric porphyrin trimers based on triphenylmethane cores

Papamicael, Cyril A.,Mongin, Olivier,Gossauer, Albert

, p. 791 - 796 (2008/02/09)

This work describes the synthesis of a new class of tripodaphyrin derivatives with a triphenylmethane core. Both C 1- and C 3ν-symmetric tetrahedral large molecules with covalently linked rigid elements were obtained.

Improved, Acid-catalyzed Iodinating Procedures for Activated Aromatics with (Diacetoxyiodo)benzene as the Oxidant

Kryska, Anna,Skulski, Lech

, p. 2501 - 2517 (2007/10/03)

Improved procedures for the oxidative, acid-catalyzed iodination of benzene, iodobenzene and several activated aromatics are presented to give mono-, di-, or triiodinated products in 40-82 percent yields. The reactions proceeded at room temperature in the anhydrous systems: arene or hetarene/diiodine/(diacetoxyiodo)benzene (2)/glacial acetic acid/acetic anhydride, acidified with catalytic amounts of concd. (98 percent) H2SO4. Within at most 15 minutes the iodine coloration faded; the following workups are explained. A similar treatment with dibromine gave tribromomesitylene (65 percent), dibromodurene (62 percent), and 2,7-dibromofluoren-9-one (73 percent). A review on the aromatic halogenation reactions with organic trivalent iodine reagents as the oxidants is presented below.
