500055-91-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 500055-91-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,0,0,5 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 500055-91:
(8*5)+(7*0)+(6*0)+(5*0)+(4*5)+(3*5)+(2*9)+(1*1)=94
94 % 10 = 4
So 500055-91-4 is a valid CAS Registry Number.

Facile regiocontrolled three-step synthesis of poly-substituted furans, pyrroles, and thiophenes: Consecutive michael addition of methyl cyanoacetate to α,β-enone, CuI-mediated aerobic oxidation, and acid-catalyzed paal-knorr synthesis

Kim, Se Hee,Lim, Jin Woo,Lim, Cheol Hee,Kim, Jae Nyoung

scheme or table, p. 620 - 624 (2012/05/05)

An efficient synthesis of poly-substituted furans, pyrroles, and thiophenes was carried out in a regiocontrolled manner via a three-step process; (i) conjugate addition of methyl cyanoacetate derivatives to α,β-enones, (ii) CuI-mediated aerobic oxidation,

Construction of 1,2,5-tricarbonyl compounds using methyl cyanoacetate as a glyoxylate anion synthon combined with copper(I) iodide-catalyzed aerobic oxidation

Kim, Se Hee,Kim, Ko Hoon,Kim, Jae Nyoung

supporting information; experimental part, p. 3335 - 3339 (2012/01/19)

A practical and efficient synthesis of various 1,2,5-tricarbonyl compounds is described. The synthesis has been carried out by a conjugate addition of methyl cyanoacetate to the β-position of α,β-unsaturated carbonyl compounds and a subsequent copper(I) iodide-catalyzed aerobic oxidation. In addition, various α-aryl- and α-alkyl-α-keto esters have been synthesized using a similar approach. Copyright
