145256-65-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145256-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,2,5 and 6 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 145256-65:
(8*1)+(7*4)+(6*5)+(5*2)+(4*5)+(3*6)+(2*6)+(1*5)=131
131 % 10 = 1
So 145256-65-1 is a valid CAS Registry Number.

2-Amino-3-cyano-dihydroindol-5-ones, III: Reports on the chemical reactivity of a new class of compounds
Eger,Frey
, p. 551 - 556 (2007/10/02)
The chemical reactivity of cytotoxic 5-indolone derivatives is examined in order to get ideas about their behaviour in biological systems. Dienone-phenol-rearrangement preserving the indole ring system could not be achieved, aromatization of 1b gives the
