Check Digit Verification of cas no

The CAS Registry Mumber 1443441-68-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,4,4 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1443441-68:
(9*1)+(8*4)+(7*4)+(6*3)+(5*4)+(4*4)+(3*1)+(2*6)+(1*8)=146
146 % 10 = 6
So 1443441-68-6 is a valid CAS Registry Number.

A co-operative effect of visible light photo-catalysis and CoFe2O4 nanoparticles for green synthesis of furans in water

Verma, Fooleswar,Singh, Puneet K.,Bhardiya, Smita R.,Singh, Manorama,Rai, Ankita,Rai, Vijai K.

supporting information, p. 4937 - 4942 (2017/07/12)

A novel approach to poly-functionalized furan synthesis is disclosed via oxidative decarboxylative [3+2] cycloaddition using co-operative catalysis by visible light and CoFe2O4 nanoparticles under ambient reaction conditions with water as a solvent. Although the reported method is efficient without catalyst in the presence of visible light (70% yield in 4 h at rt), the use of catalyst not only increases the yield (91%) but also accelerates the conversion rate (2 h at rt).

Regioselective Synthesis of Multisubstituted Furans via Copper-Mediated Coupling between Ketones and β-Nitrostyrenes

Ghosh, Monoranjan,Mishra, Subhajit,Hajra, Alakananda

, p. 5364 - 5368 (2015/05/27)

A copper-mediated intermolecular annulation of alkyl ketones and β-nitrostyrenes has been developed for the regioselective synthesis of multisubstituted furan derivatives in good yields. This protocol is applicable to both cyclic and acyclic ketones. (Che

Synthesis of polysubstituted furans via copper-mediated annulation of alkyl ketones with α,β-unsaturated carboxylic acids

Yang, Yuzhu,Yao, Jinzhong,Zhang, Yuhong

supporting information, p. 3206 - 3209 (2013/07/26)

A novel copper-mediated annulation of alkyl ketones with α,β-unsaturated carboxylic acids has been accomplished. This reaction provides a facile and regio-defined method for the synthesis of 2,3,5-trisubstituted furans from simple chemical reagents.
