Check Digit Verification of cas no

The CAS Registry Mumber 163350-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,3,3,5 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 163350-81:
(8*1)+(7*6)+(6*3)+(5*3)+(4*5)+(3*0)+(2*8)+(1*1)=120
120 % 10 = 0
So 163350-81-0 is a valid CAS Registry Number.

Catalytic Asymmetric Tandem Reaction of o-Alkynylbenzaldehydes, Amines, and Diazo Compounds

Wu, Wei,Liao, Na,Wei, Qi,Huang, Jiaying,Huang, Qi,Peng, Yungui

supporting information, p. 6872 - 6876 (2021/09/14)

An efficient asymmetric tandem reaction of o-alkynylbenzaldehydes, amines, and diazo compounds catalyzed by chiral silver imidodiphosphate has been established. Chiral 1,2-dihydroisoquinoline analogues have a tertiary stereocenter at the C1 position, and substituents at the C3 position are available with up to 97% yields and 98% ee. These products can be elaborated into the corresponding β-aminophosphonates or PARP1-inhibitor analogues.
