Check Digit Verification of cas no
The CAS Registry Mumber 113369-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,6 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 113369-19:
(8*1)+(7*1)+(6*3)+(5*3)+(4*6)+(3*9)+(2*1)+(1*9)=110
110 % 10 = 0
So 113369-19-0 is a valid CAS Registry Number.

SEMICARBAZONES AND THIOSEMICARBAZONES IN THE HETEROCYCLIC SERIES. I. REACTION OF 1-ACYLISATINS WITH THIOAROYLHYDRAZINES
Tomchin, A. B.
, p. 1180 - 1187 (2007/10/02)
The reaction of 1-acylisatins with thioaroylhydrazines can occur via two different pathways.Nucleophilic attack by the nitrogen atom of the primary amino group of thioaroylhydrazines at the C3 carbon atom of 1-acylisatins leads to the formation
