87191-81-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87191-81-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,1,9 and 1 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87191-81:
(7*8)+(6*7)+(5*1)+(4*9)+(3*1)+(2*8)+(1*1)=159
159 % 10 = 9
So 87191-81-9 is a valid CAS Registry Number.

Nitrosation of 2-Arylamino- and Alkylamino-2-thiazolines
Rao, K. V.,Nizar, P. N. H.,Chauhan, S. M. S.
, p. 974 - 976 (2007/10/02)
The N-nitrosation of 2-arylamino- and alkylamino-2-thiazolines gives the exocyclic or endocyclic nitrosated products depending on the nature of reagents used.The structures of these nitrosoproducts have been confirmed by PMR and 13C NMR spectral data.
