76159-78-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76159-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,5 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 76159-78:
(7*7)+(6*6)+(5*1)+(4*5)+(3*9)+(2*7)+(1*8)=159
159 % 10 = 9
So 76159-78-9 is a valid CAS Registry Number.

The Synthesis of the Dimethoxyisatins
Taylor, A.
, p. 4154 - 4171 (2007/10/02)
Preparations of all 6 dimethoxyisatins are described.The methods of synthesis of these compounds from anilines have been compared, the route via the 3-(methylthio)oxindoles giving, in general, the best yield.These isatins are strikingly different in colou
