103966-30-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 103966-30-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,9,6 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 103966-30:
(8*1)+(7*0)+(6*3)+(5*9)+(4*6)+(3*6)+(2*3)+(1*0)=119
119 % 10 = 9
So 103966-30-9 is a valid CAS Registry Number.

PICRYL DERIVATIVES OF ECETOACETIC ESTER AND ACETONE. REACTION WITH BASES
Onys'ko, P. P.,Proklina, N. V.,Gololobov, Yu. G.
, p. 1504 - 1508 (2007/10/02)
The reactions of picrylacetoacetic ester and picrylacetone with bases (alcoholates, amines, phosphine imine compounds) lead to deprotonation of the carbonyl part of the molecule.With the acetoacetic ester anion trinitrobenzene forms a stable 1:1 ? complex
