Check Digit Verification of cas no

The CAS Registry Mumber 881041-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,1,0,4 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 881041-55:
(8*8)+(7*8)+(6*1)+(5*0)+(4*4)+(3*1)+(2*5)+(1*5)=160
160 % 10 = 0
So 881041-55-0 is a valid CAS Registry Number.

Iron-catalyzed inexpensive and practical synthesis of N-substituted pyrroles in water

Azizi, Najmedin,Khajeh-Amiri, Alireza,Ghafuri, Hossein,Bolourtchian, Mohammad,Saidi, Mohammad Reza

, p. 2245 - 2248 (2009)

An operationally simple, practical, and economical protocol for iron(III) chloride catalyzed Paal-Knorr pyrrole synthesis in water in good to excellent yields has been developed. Several N-substituted pyrroles are readily prepared from the reaction of 2,5-dimethoxytetrahydrofuran and aryl/alkyl, sulfonyl and acyl amines under very mild reaction conditions.

Phenylpyrroles, a new chemolibrary virtual screening class of 5-HT 7 receptor ligands

Paillet-Loilier, Magalie,Fabis, Frederic,Lepailleur, Alban,Bureau, Ronan,Butt-Gueulle, Sabrina,Dauphin, Francois,Delarue, Catherine,Vaudry, Hubert,Rault, Sylvain

, p. 3753 - 3757 (2007/10/03)

Virtual screening studies have identified a series of phenylpyrroles as novel 5-HT7 receptor ligands. The synthesis and the affinity for the 5-HT7 receptor of these phenylpyrroles are described. Some of these compounds exhibited high affinity for the 5-HT7 receptors.
