89175-04-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89175-04-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,7 and 5 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 89175-04:
(7*8)+(6*9)+(5*1)+(4*7)+(3*5)+(2*0)+(1*4)=162
162 % 10 = 2
So 89175-04-2 is a valid CAS Registry Number.

A convenient method was developed for obtaining 2-N-hydroxy-3-keto-1-phenyl-1,3-dihydropyrroloindoles by reaction of indole-2-hydroxamic acid with substituted benzaldehydes.Complex compounds of trivalent iron salts with cyclic hydroxamic acids were isolated.
