86785-18-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86785-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,7,8 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 86785-18:
(7*8)+(6*6)+(5*7)+(4*8)+(3*5)+(2*1)+(1*8)=184
184 % 10 = 4
So 86785-18-4 is a valid CAS Registry Number.

Synthesis of 7,11,12-Trimethylbenzanthracene
Newman, Melvin S.
, p. 3249 - 3251 (2007/10/02)
Reaction of 1-naphthylmagnesium bromide with 3-methylphthalic anhydride gave an 86percent yield of a mixture of mostly 2-methyl-6-(1-naphthoyl)benzoic acid (2) and a little 3-methyl-2-(1-naphthoyl)benzoic acid (3).Heating this mixture with 80percent sulfu
