94204-12-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94204-12-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,2,0 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 94204-12:
(7*9)+(6*4)+(5*2)+(4*0)+(3*4)+(2*1)+(1*2)=113
113 % 10 = 3
So 94204-12-3 is a valid CAS Registry Number.

ANODIC SYNTHESIS OF BUTENOLIDES FROM β-ETHYLENIC ESTERS DOUBLE CYCLIZATION IN THE PRESENCE OF OLEFINS
Delaunay, J.,Orliac-Le Moing, A.,Simonet, J.
, p. 7089 - 7094 (2007/10/02)
Anodic oxidation of β-ethylenic esters yields butenolides 2.In the presence of 1-phenyl-1-propene or α,β-disubstituted indenones a double cyclization takes place to yield more complex butenolides
