Check Digit Verification of cas no

The CAS Registry Mumber 151073-09-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,0,7 and 3 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 151073-09:
(8*1)+(7*5)+(6*1)+(5*0)+(4*7)+(3*3)+(2*0)+(1*9)=95
95 % 10 = 5
So 151073-09-5 is a valid CAS Registry Number.

Synthesis of modified aldonic acids and studies of their substrate efficiency for dihydroxy acid dehydratase (DHAD)

Limberg, Gerrit,Thiem, Joachim

, p. 349 - 356 (2007/10/03)

Modified aldopentonic and aldohexonic acids were synthesized in order to study the electronic requirements for a successful enzymatic conversion into their corresponding 2-keto 3-deoxy analogues by dihydroxy acid dehydratase (DHAD), an enzyme from the biosynthetic pathway of branched chain amino acids. Analytical tests with the novel artificial substrates (18)-(21) and (27) provided evidence that the amount of conversion could be enhanced by replacement of the hydroxy group at C 4 of L-arabinonic acid (21) with less electron-withdrawing, ambivalent or electron-donating substituents. Modified aldohexonic acids were no substrates for DHAD, perhaps due to less perfect binding to the active site presumably for steric reasons. For 4-deoxy-L-threo-pentonic acid (18) the enzymatic conversion into 3,4-dideoxy-2-ketopentonic acid (29) by DHAD could be achieved on a preparative scale.
