Synthesis
The aryl sulfonyl chloride (10.0 mmol, 1.0 equiv) was dissolved in 30 mL water. Sodium sulfite (16.0 mmol, 1.6 equiv) and sodium bicarbonate (16.0 mmol, 1.6 equiv) were added, and the reaction mixture was refluxed for 3 h. The water was evaporated, and ethanol was added to the residue. The suspension was heated for 10 min, cooled, and filtered through a 20 μm polyethylene frit. This was repeated twice with the residue from the filtration. The ethanol fractions were combined, and the solvent was evaporated under vacuum, The sodium arylsulfinates were isolated as white powders.
Check Digit Verification of cas no
The CAS Registry Mumber 868858-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,8,8,5 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 868858-48:
(8*8)+(7*6)+(6*8)+(5*8)+(4*5)+(3*8)+(2*4)+(1*8)=254
254 % 10 = 4
So 868858-48-4 is a valid CAS Registry Number.
