Check Digit Verification of cas no

The CAS Registry Mumber 321658-65-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,6,5 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 321658-65:
(8*3)+(7*2)+(6*1)+(5*6)+(4*5)+(3*8)+(2*6)+(1*5)=135
135 % 10 = 5
So 321658-65-5 is a valid CAS Registry Number.

Pd-Catalyzed Asymmetric C-H Bond Activation for the Synthesis of P-Stereogenic Dibenzophospholes

Li, Zhen,Lin, Zi-Qi,Yan, Chao-Guo,Duan, Wei-Liang

supporting information, p. 3916 - 3920 (2019/11/14)

Pd-catalyzed asymmetric C-H bond activation for the synthesis of P-stereogenic dibenzophospholes was efficiently achieved via two types of catalytic systems. Chiral phosphoric amides/acids as ligands provided the products with up to 5:95 er, and (R)-segph
