Check Digit Verification of cas no

The CAS Registry Mumber 199742-37-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,4 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 199742-37:
(8*1)+(7*9)+(6*9)+(5*7)+(4*4)+(3*2)+(2*3)+(1*7)=195
195 % 10 = 5
So 199742-37-5 is a valid CAS Registry Number.

Direct catalytic asymmetric three-component Kabachnik-fields reaction

Cheng, Xu,Goddard, Richard,Buth, Gernot,List, Benjamin

, p. 5079 - 5081 (2008)

(Chemical Equation Presented) As mimics of α-amino acids, α-amino phosphonates have great promise as antibacterial and anti-HIV agents as well as protease inhibitors. Racemic α-branched aldehydes react, in the presence the new chiral phosphoric acid catalyst 1, directly with p-anisidine (PMPNH2) and a phosphite to furnish β-branched α-amino phosphonates highly diastereoselectively and enantioselectively. Anth = anthracenyl.
