250778-98-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 250778-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,7,7 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 250778-98:
(8*2)+(7*5)+(6*0)+(5*7)+(4*7)+(3*8)+(2*9)+(1*8)=164
164 % 10 = 4
So 250778-98-4 is a valid CAS Registry Number.

Enantioselective parallel synthesis using polymer-supported chiral Co(salen) complexes
Peukert, Stefan,Jacobsen, Eric N.
, p. 1245 - 1248 (1999)
(matrix presented) The kinetic resolution of epoxides with phenols catalyzed by a polymer-supported Co(salen) complex is applied to the first enantioselective catalytic synthesis of parallel libraries. The corresponding 1-aryloxy-2-alcohols are obtained i
