Check Digit Verification of cas no
The CAS Registry Mumber 42520-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42520-90:
(7*4)+(6*2)+(5*5)+(4*2)+(3*0)+(2*9)+(1*0)=91
91 % 10 = 1
So 42520-90-1 is a valid CAS Registry Number.

The first synthesis of fluorine-containing 2-thienyliodonium salts was accomplished using cascade iodination-fluorination. According to this methodology, thiophene is first converted to bis(2-thienyl)iodonium hexafluorophosphate using an electrophilic iodination reaction. Upon heating with potassium fluoride, this salt undergoes regioselective fluorination producing 2-fluorothiophene. 2-Fluorothiophene is then iodinated again to yield fluorothienyliodonium salts.
