Check Digit Verification of cas no

The CAS Registry Mumber 128850-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,5 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128850-87:
(8*1)+(7*2)+(6*8)+(5*8)+(4*5)+(3*0)+(2*8)+(1*7)=153
153 % 10 = 3
So 128850-87-3 is a valid CAS Registry Number.

Metalloporphyrin-promoted rearrangement of 2-alkyloxaziridines

Suda,Umehara,Hino

, p. 839 - 841 (1990)

Transformation of 2-alkyloxaziridines to the corresponding amides is efficiently catalyzed by high-valent metalloporphyrins. This novel rearrangement was used to create a peptide bond and the precursor of a dipeptide ''aspartame'' was obtained in good yield.
