1216-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1216-12-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,1 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1216-12:
(6*1)+(5*2)+(4*1)+(3*6)+(2*1)+(1*2)=42
42 % 10 = 2
So 1216-12-2 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
