Methanesulfonamide, N-butyl-, also known as N-butyl methanesulfonamide or N-Butyl methanesulfonamide, is an organic compound with the chemical formula C5H11NO2S. It is a colorless liquid with a molecular weight of 149.21 g/mol. Methanesulfonamide, N-butyl- is characterized by the presence of a methanesulfonamide group (CH3SO2NH-) attached to a butyl chain (C4H9-). Methanesulfonamide, N-butyl-, is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other chemical products. It is also known for its potential applications in the production of dyes and pigments. Due to its reactivity and functional groups, it is essential to handle Methanesulfonamide, N-butyl- with care, as it may have hazardous properties and require proper safety measures during its use and storage.

Check Digit Verification of cas no

The CAS Registry Mumber 3989-40-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,8 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 3989-40:
(6*3)+(5*9)+(4*8)+(3*9)+(2*4)+(1*0)=130
130 % 10 = 0
So 3989-40-0 is a valid CAS Registry Number.

Gold-Catalyzed 1,4-Carbooxygenation of 3-En-1-ynamides with Allylic and Propargylic Alcohols via Non-Claisen Pathways

Giri, Sovan Sundar,Lin, Li-Hsuan,Jadhav, Prakash Daulat,Liu, Rai-Shung

, p. 590 - 596 (2017)

Gold-catalyzed 1,4-carbooxygenations of 3-en-1-ynamides with allylic alcohols and propargylic alcohols yield α,β-unsaturated amides through non-Claisen pathways; the mechanisms involve ionization of the initial gold enol ethers to form C-bound gold dienolates that capture allylic or propargylic cations to yield the observed products. Our18O-labeling experiments exclude a direct gold-catalyzed allylation or propargylation on these 3-en-1-ynamides. (Figure presented.).
