Check Digit Verification of cas no

The CAS Registry Mumber 205651-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,6,5 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 205651-84:
(8*2)+(7*0)+(6*5)+(5*6)+(4*5)+(3*1)+(2*8)+(1*4)=119
119 % 10 = 9
So 205651-84-9 is a valid CAS Registry Number.

Synthesis of chiral β-aminophosphonates via Rh-catalyzed asymmetric hydrogenation of β-amido-vinylphosphonates

Kadyrov, Renat,Holz, Jens,Schaeffner, Benjamin,Zayas, Odalys,Almena, Juan,Boerner, Armin

, p. 1189 - 1192 (2008)

The Rh-catalyzed asymmetric hydrogenation of prochiral β-N-acetylamino-vinylphosphonates allows the preparation of chiral β-N-acetylamino-phosphonates with excellent yields (up to 100%) and high enantioselectivities (up to 92% ee). The reaction is strongl

Asymmetric hydrogenation of α- And β-enamido phosphonates: Rhodium(I)/monodentate phosphoramidite catalyst

Zhang, Jinzhu,Li, Yang,Wang, Zheng,Ding, Kuiling

supporting information; scheme or table, p. 11743 - 11747 (2012/01/03)

High efficiency and enantioselectivity have been achieved in the Rh I-catalyzed asymmetric hydrogenation of α- and β-enamido phosphonates using a monophosphoramidite as the chiral ligand (see scheme; cod=1,5-cyclooctadiene), thus affording the optically active amino phosphonates with a turnover frequency of up to 1800 h-1 and high ee values.
