91759-85-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91759-85-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,5 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91759-85:
(7*9)+(6*1)+(5*7)+(4*5)+(3*9)+(2*8)+(1*5)=172
172 % 10 = 2
So 91759-85-2 is a valid CAS Registry Number.

Treatment of 3-phenyl- or 3-(2-naphthyl)-2H-thietes with trimethyl- or triethyloxonium tetrafluoroborate or with methyl trifluoromethansulfonate yields colorless S-alkylthiacyclobutenium salts.They react with cyanide ion to give both ring opened and dealk
