1427298-78-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1427298-78-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,7,2,9 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1427298-78:
(9*1)+(8*4)+(7*2)+(6*7)+(5*2)+(4*9)+(3*8)+(2*7)+(1*8)=189
189 % 10 = 9
So 1427298-78-9 is a valid CAS Registry Number.

A simple enantioselective route toward (R)- and (S)-Rolipram via anhydride desymmetrization
Ivsic, Trpimir,Hamersak, Zdenko
, p. 217 - 222 (2013/04/23)
A highly enantioselective metal-free synthesis of both enantiomers of Rolipram is reported. The key stereoinductive step is a cinchona alkaloid catalyzed opening of a cyclic anhydride prepared from isovanillin, where both enantiomers are available using t
