Check Digit Verification of cas no

The CAS Registry Mumber 98750-94-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,5 and 0 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98750-94:
(7*9)+(6*8)+(5*7)+(4*5)+(3*0)+(2*9)+(1*4)=188
188 % 10 = 8
So 98750-94-8 is a valid CAS Registry Number.

Corey-Chaykovsky Cyclopropanation of Nitronaphthalenes: Access to Benzonorcaradienes and Related Systems

Antoniak, Damian,Barbasiewicz, Micha?

supporting information, p. 9320 - 9325 (2019/11/19)

Nitronaphthalene derivatives react as Michael acceptors in the Corey-Chaykovsky reaction with alkyl phenyl selenones and alkyl diphenyl sulfonium salts. Mechanistic studies reveal that sterically demanding substituents at the carbanionic center favor formation of cyclopropanes and suppress competitive β-elimination to the alkylated products. The transformation, demonstrated also on heterocyclic nitroquinoline and nitroindazolines, is an example of transition metal-free dearomatization method.
