Check Digit Verification of cas no

The CAS Registry Mumber 1259091-97-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,9,0,9 and 1 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1259091-97:
(9*1)+(8*2)+(7*5)+(6*9)+(5*0)+(4*9)+(3*1)+(2*9)+(1*7)=178
178 % 10 = 8
So 1259091-97-8 is a valid CAS Registry Number.

Montmorillonite K-10 catalyzed Mannich reaction: Synthesis of aminonaphthoquinone derivatives from Lawsone

Jayashree, Sankaranarayanan,Shivashankar, Kalegowda

supporting information, p. 1805 - 1815 (2018/06/25)

An efficient one-pot protocol for the synthesis of 2-((substituted amino)(4-phenyl)methyl)-3-hydroxy-naphthalene-1,4-dione derivatives has been developed by the three-component reaction of 2-hydroxy-naphthalene-1,4-dione, aromatic aldehydes and anilines/heterocyclic amines using montmorillonite K-10 as a catalyst. The advantages of this method include short reaction time, excellent yield and easy work-up.

Synthesis of fluorescent hydroxyl naphthalene-1,4-dione derivatives by a three-component reaction in water

Dabiri, Minoo,Tisseh, Zeinab Noroozi,Bazgir, Ayoob

experimental part, p. 63 - 69 (2011/07/07)

An efficient one-pot synthesis of fluorescent hydroxyl naphthalene-1,4- dione derivatives by a simple, atom-economical and three-component reaction of 2- hydroxynaphthalene-1,4-dione, aromatic aldehydes and heterocyclic or carbocyclic amines in the presence of a catalytic amount of InCl3 in refluxing water is reported. The structures of the compounds were confirmed by IR, 1H NMR, 13C NMR, and elemental analysis. UV- visible absorption coefficient, maximum wavelength and fluorescence emission wavelength were measured in methanol. The products were fluorescent in solution emitting at green light (546-560 nm). The advantages of this procedure are mild reaction conditions, high yields of products, operational simplicity and easy work-up procedures. The workup of these very clean reactions involves only a filtration and simple washing step with EtOH.
