865303-09-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 865303-09-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,3,0 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 865303-09:
(8*8)+(7*6)+(6*5)+(5*3)+(4*0)+(3*3)+(2*0)+(1*9)=169
169 % 10 = 9
So 865303-09-9 is a valid CAS Registry Number.

4-Substituted prolines as organocatalysts for aldol reactions
Bellis, Evagelos,Kokotos, George
, p. 8669 - 8676 (2007/10/03)
A series of 4-substituted prolines were prepared and evaluated as organocatalysts for asymmetric aldol reactions. Using (2S,4R)-4- camphorsulfonyloxy-proline, the aldol products were obtained in much higher enantiomeric excess in comparison to that observ
