1299491-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1299491-31-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,9,4,9 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1299491-31:
(9*1)+(8*2)+(7*9)+(6*9)+(5*4)+(4*9)+(3*1)+(2*3)+(1*1)=208
208 % 10 = 8
So 1299491-31-8 is a valid CAS Registry Number.

Catalytic asymmetric hydrogenation of N-Boc-imidazoles and oxazoles
Kuwano, Ryoichi,Kameyama, Nao,Ikeda, Ryuhei
, p. 7312 - 7315 (2011/06/24)
Substituted imidazoles and oxazoles were respectively hydrogenated into the corresponding chiral imidazolines and oxazolines (up to 99% ee). The highly enantioselective hydrogenation was achieved by using the chiral ruthenium catalyst, which is generated
