Check Digit Verification of cas no

The CAS Registry Mumber 1277187-96-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,7,1,8 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1277187-96:
(9*1)+(8*2)+(7*7)+(6*7)+(5*1)+(4*8)+(3*7)+(2*9)+(1*6)=198
198 % 10 = 8
So 1277187-96-8 is a valid CAS Registry Number.

Biocatalytic enantioselective oxidative C-C coupling by aerobic C-H activation

Schrittwieser, Joerg H.,Resch, Verena,Sattler, Johann H.,Lienhart, Wolf-Dieter,Durchschein, Katharina,Winkler, Andreas,Gruber, Karl,MacHeroux, Peter,Kroutil, Wolfgang

, p. 1068 - 1071 (2011/04/22)

Bridging the gap: The berberine bridge enzyme (BBE) was employed for the first preparative oxidative biocatalytic C-C coupling that leads to a new intramolecular bond. This unique transformation requires O2 as sole stoichiometric oxidant and gives access to novel optically pure (S)-berbine 2 and (R)-1-benzyl-1,2,3,4-tetrahydroisoquinoline 1 alkaloid derivatives by kinetic resolution.
