139014-48-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139014-48-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,0,1 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139014-48:
(8*1)+(7*3)+(6*9)+(5*0)+(4*1)+(3*4)+(2*4)+(1*8)=115
115 % 10 = 5
So 139014-48-5 is a valid CAS Registry Number.

Method for the Direct Enantioselective Synthesis of Chiral Primary α-Amino Ketones by Catalytic α-Amination
Han, Yixin,Corey
, p. 283 - 286 (2019)
A useful catalytic enantioselective approach has been developed for the synthesis of chiral ketamine analogs using Rh(II)-catalyzed amination of triisopropylsilyl enol ethers to form α-amino ketones with O-(4-nitrophenyl)hydroxylamine as nitrogen donor in 81-91% ee.
