Check Digit Verification of cas no

The CAS Registry Mumber 74033-50-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,3 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74033-50:
(7*7)+(6*4)+(5*0)+(4*3)+(3*3)+(2*5)+(1*0)=104
104 % 10 = 4
So 74033-50-4 is a valid CAS Registry Number.

Biogenesis of Epidithiadiketopiperazines. Synthesis of Three Isomeric (β-Aminoethyl)benzene Oxides

Rastetter, William H.,Nummy, Larry J.

, p. 3149 - 3155 (1980)

Three isomeric amine-substituted arene oxides have been synthesized to serve as models for the postulated involvement of amino acid derived arene oxides during the biosyntheses of various epidithiadiketopiperazines.No biogenetic-type reactivity was noted for the arene oxides.In all three cases aromatization rather than amine/epoxide cyclization was observed.The failure to duplicate the presumed in vivo reactivity of aminoarene oxides is discussed in terms of possible enzyme-mediated cyclizations in the natural systems.
