Check Digit Verification of cas no

The CAS Registry Mumber 1210820-90-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,0,8,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1210820-90:
(9*1)+(8*2)+(7*1)+(6*0)+(5*8)+(4*2)+(3*0)+(2*9)+(1*0)=98
98 % 10 = 8
So 1210820-90-8 is a valid CAS Registry Number.

Concise synthesis and applications of enantiopure spirobiphenoxasilin-diol and its related chiral ligands

The development of chiral architectures for chiral ligand and catalyst discovery is essential for asymmetric catalysis. Herein, we report the concise synthesis of a Si-centered spirocyclic skeleton, spirobiphenoxasilin-diol (SPOSiOL), and its derived chiral ligands. Using the chemical resolution method, the optical SPOSiOL could be obtained in high yield on a gram scale. Preliminary studies indicated that this ligand scaffold has great potential in transition metal-catalyzed asymmetric reactions. This finding further highlights that the Si-centered spirocyclic scaffolds are of great value in asymmetric catalysis. This journal is
