125228-97-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125228-97-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,2 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 125228-97:
(8*1)+(7*2)+(6*5)+(5*2)+(4*2)+(3*8)+(2*9)+(1*7)=119
119 % 10 = 9
So 125228-97-9 is a valid CAS Registry Number.

REGIOSELECTIVITY OF DIELS-ALDER ADDITIONS OF 1-ACETYLVINYL ARENECARBOXYLATES
Aguilar, Raul,Reyes, Alicia,Tamariz, Joaquin
, p. 865 - 868 (2007/10/02)
The Diels-Alder addition of "captodative" dienophiles 1-acetylvinyl arenecarboxylates 1b,1d and 1e to 1- and 2-substituted dienes was found highly regioselective.The rate and regioselectivity of this reaction were improved by Lewis acid catalysis.
