Check Digit Verification of cas no
The CAS Registry Mumber 143505-00-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,0 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 143505-00:
(8*1)+(7*4)+(6*3)+(5*5)+(4*0)+(3*5)+(2*0)+(1*0)=94
94 % 10 = 4
So 143505-00-4 is a valid CAS Registry Number.

The invention discloses a synthesizing and purifying method for 4-aminouracil. The method comprises the following steps of: (a) adding solid cyanoacetic acid, urea and acetic oxide into a reaction bottle for reacting for 1-5 hours at the temperature of 40-120 DEG C; (b) adding hydroxide into the step (a) for reacting for 1-3 hours; (c) neutralizing by using inorganic acid and adding acetone, and purifying a product by means of double solvent treatment. The method is simple in process and convenient to carry out; the obtained product is high in purity and high in yield.
