Check Digit Verification of cas no

The CAS Registry Mumber 134938-94-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,3 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 134938-94:
(8*1)+(7*3)+(6*4)+(5*9)+(4*3)+(3*8)+(2*9)+(1*4)=156
156 % 10 = 6
So 134938-94-6 is a valid CAS Registry Number.

7-Aminoaziridinomitosenes: Synthesis, Structure, and Chemistry

Han, Insook,Kohn, Harold

, p. 4648 - 4653 (1991)

7-Aminoleucoaziridinomitosene (2a) has been proposed as a key intermediate in the reductive activation process for the antineoplastic agent, mitomycin C (1a).Little is known about 2a and its oxidised equivalent, 7-aminoaziridinomitosene (3a).An expedient electrochemical procedure for 3a and the corresponding N-methyl analogue 3b has been developed.NMR spectral studies of 3a in DMF-d7 and DMSO-d6 provided important information concerning the solution-state structure for this adduct.Factors controlling the aziridine ring-opening process under reductive and nonreductive conditions have been determined, as well as evidence for the intermediacy of 2a in the reductive activation cascade of 1a.
