98236-95-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98236-95-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,3 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98236-95:
(7*9)+(6*8)+(5*2)+(4*3)+(3*6)+(2*9)+(1*5)=174
174 % 10 = 4
So 98236-95-4 is a valid CAS Registry Number.

ACYLHYDRAZONES OF 3H-INDOL-3-ONE
Berdinskii, I. S.,Maslivets, A. N.,Orlova, L. D.
, p. 814 - 816 (2007/10/02)
The reaction of 3-ethoxalyl- and acetylhydrazones of isatin with arylmagnesium bromide leads to the glycoloyl- and acetylhydrazones of 2-aryl-3H-indol-3-one as a result of the participation of the α-carbonyl group of the isatin ring in the reaction.
