Check Digit Verification of cas no
The CAS Registry Mumber 489-59-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,8 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 489-59:
(5*4)+(4*8)+(3*9)+(2*5)+(1*9)=98
98 % 10 = 8
So 489-59-8 is a valid CAS Registry Number.

Reactions of Alkoxyuridines with Ammonia (l)
Mathews, Robert A.,Stoehrer, Gerhard
, p. 1601 - 1602 (2007/10/02)
2-Alkoxy- and 4-alkoxyuridines were converted into isocytidine and cytidine by reaction with ammonia at room temperature.Reaction with hydrogen sulfide produced 2-thio- and 4-thiouridine but the reaction was incomplete.The reaction may be helpful in the identification of alkylated pyrimidine nucleosides in DNA.
