Thiocyanic acid, with the chemical formula HSCN, is an acidic compound that contains sulfur and nitrogen. It is a colorless, unstable, and highly toxic liquid that readily decomposes into hydrogen sulfide (H2S) and cyanide (CN). Thiocyanic acid is used in various applications, including the production of dyes, pharmaceuticals, and pesticides. Iron (III)-thiocyanate, on the other hand, is a coordination compound formed when iron (III) ions (Fe3+) react with thiocyanate ions (SCN-). thiocyanic acid ; iron (III)-compound is known for its blood-red color and is often used in qualitative analysis to test for the presence of iron (III) ions. The reaction between iron (III) ions and thiocyanate ions can be represented by the following equation: Fe3+ + 3SCN- → Fe(SCN)3.
The CAS Registry Mumber 5936-20-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,3 and 6 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5936-20: (6*5)+(5*9)+(4*3)+(3*6)+(2*2)+(1*0)=109 109 % 10 = 9 So 5936-20-9 is a valid CAS Registry Number.
