Check Digit Verification of cas no
The CAS Registry Mumber 16317-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,3,1 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 16317-78:
(7*1)+(6*6)+(5*3)+(4*1)+(3*7)+(2*7)+(1*8)=105
105 % 10 = 5
So 16317-78-5 is a valid CAS Registry Number.

N-3-alkylation of uracil and derivatives via N-1-BOC protection
Jaime-Figueroa,Zamilpa,Guzman,Morgans D.J.
, p. 3739 - 3746 (2007/10/03)
An easy and efficient synthesis of 3-alkyluracils is described. Thus, BOC-protection at N-1 of uracil permits selective alkylation at N-3. This protecting group can be removed under very mild conditions.
