Check Digit Verification of cas no

The CAS Registry Mumber 1320256-66-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,2,0,2,5 and 6 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1320256-66:
(9*1)+(8*3)+(7*2)+(6*0)+(5*2)+(4*5)+(3*6)+(2*6)+(1*6)=113
113 % 10 = 3
So 1320256-66-3 is a valid CAS Registry Number.

Iridium/f-Amphox-Catalyzed Asymmetric Hydrogenation of Styrylglyoxylamides

Wang, Simin,Yu, Yuena,Wen, Jialin,Zhang, Xumu

, p. 2203 - 2207 (2018/09/29)

We report an iridium-catalyzed asymmetric hydrogenation reaction for the preparation of chiral homophenylalanine derivatives. Catalyzed by an iridium/f-amphox complex, the asymmetric hydrogenation of styrylglyoxylamides was conducted smoothly with turnover numbers of up to 10,000 and up to 98% ee. This method was successfully applied in a synthesis of a fragment of benazepril, a drug used for the treatment of high blood pressure.

Synthesis and biological evaluation of α-ketoamides as inhibitors of the Dengue virus protease with antiviral activity in cell-culture

Steuer, Christian,Gege, Christian,Fischl, Wolfgang,Heinonen, Karl H.,Bartenschlager, Ralf,Klein, Christian D.

, p. 4067 - 4074 (2011/08/21)

The development of small molecule inhibitors of the viral protease is of considerable interest for the treatment of emergent flaviviral diseases such as Dengue or West Nile fever. Until today little progress has been made in finding drug-like compounds th
