Check Digit Verification of cas no

The CAS Registry Mumber 142683-15-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,6,8 and 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 142683-15:
(8*1)+(7*4)+(6*2)+(5*6)+(4*8)+(3*3)+(2*1)+(1*5)=126
126 % 10 = 6
So 142683-15-6 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

supporting information, p. 283 - 286 (2019/01/10)

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.
