Check Digit Verification of cas no
The CAS Registry Mumber 402849-08-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,2,8,4 and 9 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 402849-08:
(8*4)+(7*0)+(6*2)+(5*8)+(4*4)+(3*9)+(2*0)+(1*8)=135
135 % 10 = 5
So 402849-08-5 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.
