Check Digit Verification of cas no

The CAS Registry Mumber 183134-53-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,1,3 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 183134-53:
(8*1)+(7*8)+(6*3)+(5*1)+(4*3)+(3*4)+(2*5)+(1*3)=124
124 % 10 = 4
So 183134-53-4 is a valid CAS Registry Number.

Comparison of the substrate specificity of type I and type II dehydroquinases with 5-deoxy- and 4,5-dideoxy-dehydroquinic acid

Harris, Joanna M.,Watkins, William J.,Hawkins, Alastair R.,Coggins, John R.,Abell, Chris

, p. 2371 - 2377 (2007/10/03)

Syntheses of 5-deoxydehydroquinic acid and 4,5-dideoxydehydroquinic acid from quinic acid are described. These substrate analogues were tested against the mechanistically-distinct type I and type II dehydroquinases. The C-4 hydroxy group of the substrate is shown to be important for imine formation on the type I enzyme but appears not to contribute significantly to specificity on the type II dehydroquinase.
