55573-06-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55573-06-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,5,7 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55573-06:
(7*5)+(6*5)+(5*5)+(4*7)+(3*3)+(2*0)+(1*6)=133
133 % 10 = 3
So 55573-06-3 is a valid CAS Registry Number.

, p. 337 - 341 (2007/10/02)
Nucleophilic ring opening (cleavage b of the N-CO bond) of the "activated" pyrrolidones 1a-f and 2d produces the amidoethylated malonic acids 3a-f and 4d as well as their derivatives (diamide 13a, dihydrazide 11d) in good yields.The exocyclic ester functi
