Check Digit Verification of cas no
The CAS Registry Mumber 85-83-6 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 85-83:
(4*8)+(3*5)+(2*8)+(1*3)=66
66 % 10 = 6
So 85-83-6 is a valid CAS Registry Number.

The invention discloses a method of preparing solvent red 24. The method comprises the steps of: feeding ortho-toluidine and methanol into a reactor, dropwise adding 30wt% of hydrochloric acid at 20-25 DEG C, cooling to 2-5 DEG C, dropwise adding 40wt% of sodium nitrite solution, performing thermal insulation for 3h, heating to a room temperature for thermal insulation for 2h, adding soft water, performing stirring and filtering, washing till a pH (potential of hydrogen) of filtrate is neutral, performing drying, feeding ortho-toluidine, the soft water and a single coupling material into the reactor, dropwise adding 30wt% of hydrochloric acid at 20-25 DEG C, cooling to 2-5 DEG C, dropwise adding 20wt% of sodium nitrite solution, performing thermal insulation for 4h, dropwise adding a mixedsolution of 2-naphthol and 5% alkaline liquor at 2-5 DEG C, performing thermal insulation for 2h, regulating the pH, performing thermal insulation for 5h, re-measuring the pH, performing filtering, and repeatedly cleaning and drying a filter cake. According to the method, reaction time is shortened; a reaction is relatively thorough; a product yield is increased by approximately 30%; almost no byproduct is generated; and a product is excellent in color light and strength.
