Synthesis

The synthesis of methyl 6-(trifluoromethylsulfonyloxy)-1-naphthoate is as follows:Diisopropylethyiamine (2.35 mL, 13,5 mmol) and irifluoromethanesuifonic anhydride (0,95 mL, 5.6 mmol) were added sequentially to a solution of methyl 6-hydroxy- l- naphthoate ( 10 mg, 4.5 mmol) in CH2C12?(60 mL) at - 78 °C. After 1 h at - 78 °C, the reaction mixture was poured into saturated aqueous NH4C1 (30 mL). The resulting mixture was extracted with CH2CI2?(3x50 mL). The combined organic phase was washed with brine (50 mL) then dried ( a2S0 ), filtered and concentrated in vacuo. The resulting residue was purified on 80 g silica gel (100% hexanes - 100% EtOAc, gradient) to afford 1 ,45 g (96%) of methyl 6-(trifluoromethylsulfonyloxy)-1-naphthoate.

Check Digit Verification of cas no

The CAS Registry Mumber 255050-65-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,5,0,5 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 255050-65:
(8*2)+(7*5)+(6*5)+(5*0)+(4*5)+(3*0)+(2*6)+(1*5)=118
118 % 10 = 8
So 255050-65-8 is a valid CAS Registry Number.
