Check Digit Verification of cas no

The CAS Registry Mumber 137635-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,6,3 and 5 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137635-98:
(8*1)+(7*3)+(6*7)+(5*6)+(4*3)+(3*5)+(2*9)+(1*8)=154
154 % 10 = 4
So 137635-98-4 is a valid CAS Registry Number.

Process for preparing uracil derivatives

-

, (2008/06/13)

The present invention relates to a novel process for preparing uracil derivatives useful as intermediates in the synthesis of uridines having antiviral or antitumor activity or useful as coadjuvants in antiviral therapy, characterized by converting a compound of the formula II into its mesylate derivative of the formula III which is the reduced to give the desired compound of the formula I: STR1 in which R1 is H, halogen, alkyl, aryl or aralkyl.

, p. 875 - 879 (2007/10/02)

A new two step synthesis of 5-alkyluracil derivatives from barbituric acids is described.Regioselective mono O-mesylation of barbituric acids, followed by desulfonylation under reductive conditions, afforded uracils in high overall yield.The reductive desulfonylation step is also discussed.
