80946-03-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80946-03-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,9,4 and 6 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80946-03:
(7*8)+(6*0)+(5*9)+(4*4)+(3*6)+(2*0)+(1*3)=138
138 % 10 = 8
So 80946-03-8 is a valid CAS Registry Number.

Synthesis of 1-Substituted 5-Cyanouracils
Wolfbeis, Otto S.
, p. 182 - 185 (2007/10/02)
Condensation of (cyanoacetyl)urea (1) with aniline and trimethoxymethane affords (3-anilino-2-cyanoacryloyl)urea (2a), which thermally cyclizes to form strongly fluorescent 5-cyano-1-phenyluracil (3a).By using 2-aminopyridine or trimethoxymethane, other u
