27349-51-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 27349-51-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,3,4 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 27349-51:
(7*2)+(6*7)+(5*3)+(4*4)+(3*9)+(2*5)+(1*1)=125
125 % 10 = 5
So 27349-51-5 is a valid CAS Registry Number.

Asymmetric transfer hydrogenation of heterocycle-containing acetophenone derivatives using N-functionalised [(benzene)Ru(II)(TsDPEN)] complexes

Barrios-Rivera, Jonathan,Xu, Yingjian,Clarkson, Guy J.,Wills, Martin

supporting information, (2021/12/02)

The application of enantiomerically-pure ruthenium(II) catalysts containing N - functionalised TsDPEN ligand to the asymmetric transfer hydrogenation of 15 examples of α-heterocyclic acetophenone derivatives is reported. Products of up to 99% ee were formed.

Mo(CO)6-INDUCED N-O BOND CLEAVAGE OF ISOXAZOLES. A CONVENIENT ROUTE TO PYRIDIN-4(1H)-ONES

Nitta, Makoto,Higuchi, Takanobu

, p. 853 - 858 (2007/10/02)

The Mo(CO)6-induced reaction of 3-methyl-5-(2-oxoalkyl)isoxazoles, which are derived through proton-abstraction of 3,5-dimethylisoxazole followed by treatment with esters, gave pyridin-4(1H)-ones in good to modest yields in a single step.
