Check Digit Verification of cas no

The CAS Registry Mumber 942274-97-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,2,2,7 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 942274-97:
(8*9)+(7*4)+(6*2)+(5*2)+(4*7)+(3*4)+(2*9)+(1*7)=187
187 % 10 = 7
So 942274-97-7 is a valid CAS Registry Number.

Asymmetric Reductive Amination/Ring-Closing Cascade: Direct Synthesis of Enantioenriched Biaryl-Bridged NH Lactams

Zhang, Yao,Liu, Yun-Qi,Hu, Le'An,Zhang, Xumu,Yin, Qin

supporting information, p. 6479 - 6483 (2020/09/02)

We report here a Ru-catalyzed enantioselective synthesis of biaryl-bridged NH lactams through asymmetric reductive amination and a spontaneous ring-closing cascade from keto esters and NH4OAc with H2 as reductant. The reaction features broad substrate generality and high enantioselectivities (up to >99percent ee). To showcase the practical utility, a highly enantioselective synthesis of 5-ethylindolobenzazepinone C, a promising antimitotic agent, has been rapidly completed. Furthermore, the amide group in the products enables versatile elaborations through directed C-H functionalization.
