54034-47-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54034-47-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,3 and 4 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 54034-47:
(7*5)+(6*4)+(5*0)+(4*3)+(3*4)+(2*4)+(1*7)=98
98 % 10 = 8
So 54034-47-8 is a valid CAS Registry Number.

Sulfur-mediated difunctionalization of internal and terminal alkynes for the synthesis of α-acetoxy ketones

Li, Pingfan,Zhang, Zhong

supporting information, (2020/02/13)

The sulfur-mediated difunctionalization of alkynes is reported to give α-acetoxy ketones in a one-pot operation under mild conditions with 19–92% yield. By using wet potassium acetate as both the aqueous base and nucleophilic reagent, both terminal alkynes and internal alkynes could be converted into the α-acetoxy ketone products.

, p. 606 - 609 (2007/10/02)

Oxazoles having functionalized carbon substituents at the C-2 position were synthesized in one step by the oxidation of ketones with iron(III) solvates of nitriles, i.e., Fe(RCN)6(ClO4)3(solvate A) or Fe(RCN)6)FeCl4)3(solvate B), in the corresponding nitriles.Keywords oxazole; ketone; oxidation; nitrile; iron(III) nitrile solvate
