89970-82-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89970-82-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,7 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 89970-82:
(7*8)+(6*9)+(5*9)+(4*7)+(3*0)+(2*8)+(1*2)=201
201 % 10 = 1
So 89970-82-1 is a valid CAS Registry Number.

Efficient Conversions of Carboxylic Acids into O-Alkyl, N-Alkyl and O,N-Dialkylhydroxamic Acids
Katritzky, Alan R.,Kirichenko, Nataliya,Rogovoy, Boris V.
, p. 2777 - 2780 (2007/10/03)
Carboxylic acids were conveniently converted into unsubstituted, N-alkyl-, O-alkyl-, and O,N-dialkylhydroxamic acids via acylbenzotriazole intermediates. The ready availability of the reagents, mild conditions, and easy handling of the intermediates are advantageous.
