Check Digit Verification of cas no

The CAS Registry Mumber 1340475-92-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,4,7 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1340475-92:
(9*1)+(8*3)+(7*4)+(6*0)+(5*4)+(4*7)+(3*5)+(2*9)+(1*2)=144
144 % 10 = 4
So 1340475-92-4 is a valid CAS Registry Number.

Visible-light photoredox-mediated oxidation of N-methyl tertiaryamines under catalyst free conditions: Direct synthesis of methylene-bridged bis-1,3-dicarbonyl compounds

Dai, Xiao-Jun,Xu, Xiao-Liang,Cheng, Dong-Ping,Li, Xiao-Nian

supporting information, p. 545 - 548 (2014/05/06)

Mediated by visible light-induced photoredox catalysis and free of other catalysts, a new and efficient synthesis of methylene-bridged bis-1,3-dicarbonyl derivatives has been developed. A variety of N-methyl tertiaryamines and 1,3-dicarbonyl compounds were investigated in this reaction.

Aerobic oxidation of a tertiary aliphatic amine under visible-light photocatalysis: Facile synthesis of methylene-bridged bis-1,3-dicarbonyl compounds

Yoo, Woo-Jin,Tanoue, Arata,Kobayashi, Shu

, p. 2764 - 2767 (2013/02/22)

Lights, camera, action! An efficient protocol for the formation of methylene-bridged bis-1,3-dicarbonyl compounds has been developed through an aerobic photocatalytic oxidative coupling reaction between 1,3-dicarbonyl compounds and a tertiary aliphatic amine. Copyright

Gold/copper-catalyzed activation of the aci-form of nitromethane in the synthesis of methylene-bridged bis-1,3-dicarbonyl compounds

Balamurugan, Rengarajan,Manojveer, Seetharaman

supporting information; experimental part, p. 11143 - 11145 (2011/11/05)

Activation of the aci-form of nitromethane using Lewis acids for the attack of carbon nucleophiles was studied. 1,3-Dicarbonyl compounds in the presence of catalytic amounts of AuCl3 or Cu(OTf)2 in nitromethane solvent could be converted into methylene-bridged bis-1,3-dicarbonyl compounds.
