Check Digit Verification of cas no

The CAS Registry Mumber 1016835-48-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,6,8,3 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1016835-48:
(9*1)+(8*0)+(7*1)+(6*6)+(5*8)+(4*3)+(3*5)+(2*4)+(1*8)=135
135 % 10 = 5
So 1016835-48-5 is a valid CAS Registry Number.

Br?nsted Acid-Catalyzed Asymmetric Ring-Closing Alkylation of Inert N-substituted Pyrroles with α, β-Unsaturated Ketones

Wei, Zhao,Zhang, Jinlong,Yang, Huameng,Jiang, Gaoxi

, p. 3694 - 3697 (2019)

A Chiral Br?nsted acid catalyzed asymmetric intramolecular ring-closing alkylation of inert pyrroles with α, β-unsaturated ketones has been developed. This approach gave a wide range of 4-phenyl-4,5-dihydro-6H-benzo[f]pyrrolo[1,2-a]azepin-6-ones in high yields with good enantioselectivities under mild reaction conditions. (Figure presented.).
