130240-26-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 130240-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,4 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130240-26:
(8*1)+(7*3)+(6*0)+(5*2)+(4*4)+(3*0)+(2*2)+(1*6)=65
65 % 10 = 5
So 130240-26-5 is a valid CAS Registry Number.

Chemo- and enantioselective hydrogenation of the activated keto group of fluorinated β-diketones

Hess, Reto,Diezi, Simon,Mallat, Tamas,Baiker, Alfons

, p. 251 - 257 (2004)

Asymmetric hydrogenation of the activated carbonyl group of 1,1,1-trifluoro-2,4-diketones was studied over Pt/Al2O3 modified by various chiral 1,2-aminoalcohols and amines. The best chiral modifiers were cinchonidine and O-methyl-cin

Cyclodehydration of fluorinated diols using the mitsunobu reaction: Highly efficient synthesis of trifluoromethylated cyclic ethers

Prakash, G. K. Surya,Do, Clement,Wang, Fang,Mathew, Thomas,Olah, George A.

experimental part, p. 1891 - 1898 (2010/08/20)

Synthesis of trifluoromethylated cyclic ethers has been achieved via the Mitsunobu cyclodehydration of fluorinated diols with high efficacy. The methodology is found to be widely applicable to the synthesis of cyclic ethers with varying ring size (3-7) fr
