Check Digit Verification of cas no

The CAS Registry Mumber 87815-75-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,8,1 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 87815-75:
(7*8)+(6*7)+(5*8)+(4*1)+(3*5)+(2*7)+(1*5)=176
176 % 10 = 6
So 87815-75-6 is a valid CAS Registry Number.

Synthesis of o-Nitroarylamines via Ipso Nucleophilic Substitution of Sulfonic Acids

Manne, Srinivasa Rao,Chandra, Jyoti,Mandal, Bhubaneswar

supporting information, p. 636 - 639 (2019/01/21)

A mild, efficient, and eco-friendly method for the synthesis of o-nitroarylamine from o-nitroaryl sulfonic acid via ipso nucleophilic aryl substitution by amine is described. The products have been obtained with good yields at room temperature without the assistance of any metal, activating agent, or toxic oxidant. This method is useful for racemization-free synthesis of N-aryl amino acid esters.
