199786-85-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 199786-85-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,9,7,8 and 6 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 199786-85:
(8*1)+(7*9)+(6*9)+(5*7)+(4*8)+(3*6)+(2*8)+(1*5)=231
231 % 10 = 1
So 199786-85-1 is a valid CAS Registry Number.

Electrophilic cyclization of amino ketals 14a and 14b with 6 M HCl at 23 deg C, followed by oxidation with air in 6M HCl at 100 deg C, gave tetrahydrophenanthridines 16a and 16b, respectively, which were transformed into the pyrrolophenanthridinium salts
