Check Digit Verification of cas no

The CAS Registry Mumber 1618668-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,6,6 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1618668-91:
(9*1)+(8*6)+(7*1)+(6*8)+(5*6)+(4*6)+(3*8)+(2*9)+(1*1)=209
209 % 10 = 9
So 1618668-91-9 is a valid CAS Registry Number.

Enantioselective hydrogenation of α,β-disubstituted nitroalkenes

Li, Shengkun,Huang, Kexuan,Zhang, Xumu

supporting information, p. 8878 - 8881 (2014/08/05)

The first highly chemo- and enantioselective hydrogenation of α,β-disubstituted nitroalkenes was accomplished with rhodium/JosiPhos-J2 as a catalyst, with the yield and enantioselectivity of up to 95% and 94%, respectively. The α-chiral nitroalkanes will provide an entry to valuable chiral amphetamines which are otherwise not so easily accessed. This journal is the Partner Organisations 2014.
