Check Digit Verification of cas no
The CAS Registry Mumber 4009-78-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,0 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4009-78:
(6*4)+(5*0)+(4*0)+(3*9)+(2*7)+(1*8)=73
73 % 10 = 3
So 4009-78-3 is a valid CAS Registry Number.

Selective acylation of phenols in boron trifluoride diethyl etherate solution and the mechanistic implication
Xiao, Zhu-Ping,Wei, Wei,Huang, Shen,Lin, Xiao-Yi,Peng, Bin,Wang, Xu-Dong,Zhang, Lei

In the presence of boron trifluoride diethyl etherate (BF3 · OEt2), direct acylation of phenols with free carboxylic acid is chemoselective and regioselective and no demethylation, if any, was observed. The para-directing effect of BF3·OEt2 is attributed to the large steric hindrance of the boron trifluoride-phenolic hydroxyl group complex, which blocks the ortho-acylation from occurrence. Microwave irradiation could not change the regioselectivity of BF3·OEt2 except the reaction time being greatly shortened.
