623-59-6 Usage
Synthesis
To a solution of acetamide (15 g, 0.25 mol) in bromine (22 g),warmed slowly with stirring, was added dropwise via syringe sodium hydroxide (10 g, 0.25 mol) in water (25 ml). The mixture was heated to bubble up. After 3 minutes additional heating, the reaction mixture was cooled down with ice bath, filtered and washed with ice water (3 × 10 ml) to give acetyl methylurea (12 g) as a white powder, which was used without further purification.
Check Digit Verification of cas no
The CAS Registry Mumber 623-59-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 623-59:
(5*6)+(4*2)+(3*3)+(2*5)+(1*9)=66
66 % 10 = 6
So 623-59-6 is a valid CAS Registry Number.
