40339-47-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40339-47-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,3,3 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40339-47:
(7*4)+(6*0)+(5*3)+(4*3)+(3*9)+(2*4)+(1*7)=97
97 % 10 = 7
So 40339-47-7 is a valid CAS Registry Number.

Unlocking the catalytic potential of tris(3,4,5-trifluorophenyl)borane with microwave irradiation

Carden, Jamie L.,Gierlichs, Lukas J.,Wass, Duncan F.,Browne, Duncan L.,Melen, Rebecca L.

supporting information, p. 318 - 321 (2019/01/09)

The catalytic activity of tris(3,4,5-trifluorophenyl)borane has been explored in the 1,2-hydroboration reactions of unsaturated substrates. Under conventional conditions, the borane was found to be active only in the hydroboration of aldehyde, ketone and imine substrates, with alkenes and alkynes not being reduced effectively. The use of microwave irradiation on the other hand has permitted alkenes and alkynes to be hydroborated in good yields.

Poly(ethylene glycol) supported liquid-phase synthesis of 1,2,4-oxadiazolines

Lin, Xu-Feng,Zhang, Jian,Cui, Sun-Liang,Wang, Yan-Guang

, p. 1569 - 1573 (2007/10/03)

The liquid-phase synthesis of oxadiazolines via 1,3-dipolar cycloaddition reaction on poly(ethylene glycol) support (PEG) is described. 1,3-Dipolar cycloadditions of nitrile oxide generated in situ on soluble polymer with a variety of imines provided a li
