204587-90-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 204587-90-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,5,8 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 204587-90:
(8*2)+(7*0)+(6*4)+(5*5)+(4*8)+(3*7)+(2*9)+(1*0)=136
136 % 10 = 6
So 204587-90-6 is a valid CAS Registry Number.

Chiral ligand-controlled asymmetric conjugate amination of enoates with lithium mesitylmethyl(trimethylsilyl)amide
Sakai, Takeo,Doi, Hirohisa,Tomioka, Kiyoshi
, p. 8351 - 8359 (2007/10/03)
Lithium mesitylmethyl(trimethylsilyl)amide behaved as a nice amination agent in a chiral ligand-controlled conjugate addition reaction of tert-butyl cinnamate to give the conjugate amination product with 99% ee in 90% yield. Other acyclic and cyclic enoat
