82297-12-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 82297-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,2,9 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 82297-12:
(7*8)+(6*2)+(5*2)+(4*9)+(3*7)+(2*1)+(1*2)=139
139 % 10 = 9
So 82297-12-9 is a valid CAS Registry Number.

CAPTO-DATIVE SUBSTITUENT EFFECTS. 12 -NEW KETENE EQUIVALENTS FOR DIELS-ALDER CYCLOADDTIONS
Stella, Lucien,Boucher, Jean-Luc
, p. 953 - 956 (2007/10/02)
We describe the use of "capto-dative" olefins 1 as novel ketene equivalents which behave as efficient dienophiles in the Diels-Alder process.
