Check Digit Verification of cas no

The CAS Registry Mumber 1294477-80-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,4,4,7 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1294477-80:
(9*1)+(8*2)+(7*9)+(6*4)+(5*4)+(4*7)+(3*7)+(2*8)+(1*0)=197
197 % 10 = 7
So 1294477-80-7 is a valid CAS Registry Number.

Consecutive Intermolecular Reductive Amination/Asymmetric Hydrogenation: Facile Access to Sterically Tunable Chiral Vicinal Diamines and N-Heterocyclic Carbenes

Chen, Ya,Pan, Yixiao,He, Yan-Mei,Fan, Qing-Hua

, p. 16831 - 16834 (2019)

A highly enantioselective iridium- or ruthenium-catalyzed intermolecular reductive amination/asymmetric hydrogenation relay with 2-quinoline aldehydes and aromatic amines has been developed. A broad range of sterically tunable chiral N,N′-diaryl vicinal diamines were obtained in high yields (up to 95 %) with excellent enantioselectivity (up to >99 % ee). The resulting chiral diamines could be readily transformed into sterically hindered chiral N-heterocyclic carbene (NHC) precursors, which are otherwise difficult to access. The usefulness of this synthetic approach was further demonstrated by the successful application of one of the chiral vicinal diamines and chiral NHC ligands in a transition-metal-catalyzed asymmetric Suzuki–Miyaura cross-coupling reaction and asymmetric ring-opening cross-metathesis, respectively.
