849411-40-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 849411-40-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,4,1 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 849411-40:
(8*8)+(7*4)+(6*9)+(5*4)+(4*1)+(3*1)+(2*4)+(1*0)=181
181 % 10 = 1
So 849411-40-1 is a valid CAS Registry Number.

Starting from (S)-aspartic acid, a flexible chemoselective approach to (S)-3-amino-2-pyrrolidinone derivatives was reported. The (S)-3-amino-2-pyrrolidinone derivatives thus synthesized are useful templates for designing medicinal interesting compounds.
