synthetic
1.5g (6.8mmol) of 7,8-dimethoxy-1,3-dihydro-2h-3-benzoaza-2-one, 1.5g (9.5mmol) of 1,3-bromochloropropane and 6ml of DMF into a flask, raise the temperature of the mixture to 40 ℃, and add 0.8g of 40% sodium hydroxide (8mmol) solution. The mixture was then heated to 60 ° C and stirred for 2 hours; Add 30 ml of ice water and stir for 1 hour under the cooling of ice water bath. Filter out solid precipitates, wash and dry. The yield of the title compound was 85%.
Description

Check Digit Verification of cas no
The CAS Registry Mumber 85175-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,1,7 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85175-59:
(7*8)+(6*5)+(5*1)+(4*7)+(3*5)+(2*5)+(1*9)=153
153 % 10 = 3
So 85175-59-3 is a valid CAS Registry Number.
