Check Digit Verification of cas no
The CAS Registry Mumber 220835-67-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,8,3 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 220835-67:
(8*2)+(7*2)+(6*0)+(5*8)+(4*3)+(3*5)+(2*6)+(1*7)=116
116 % 10 = 6
So 220835-67-6 is a valid CAS Registry Number.

Methods for making optically active 3-aminopyrrolidine-2,5-dione derivative and optically active 3-aminopyrrolidine derivative
-
Example 8, (2008/06/13)
A method for making an optically active 3-aminopyrrolidine-2,5-dione derivative represented by the formula (3) includes cyclizing an optically active asparagine ester derivative represented by the formula (1) or (2) or an acid salt thereof. The optically active 3-aminopyrrolidine-2,5-dione derivative represented by the formula (3) may be reduced to form an optically active 3-aminopyrrolidine derivative represented by the formula (9). When, in the formula (9), R1 is an unsubstituted or substituted benzyl group, the compound may be hydrogenated to obtain the corresponding 1-unsubstituted compound in which R1 is hydrogen.
