37622-78-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 37622-78-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,6,2 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37622-78:
(7*3)+(6*7)+(5*6)+(4*2)+(3*2)+(2*7)+(1*8)=129
129 % 10 = 9
So 37622-78-9 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

, p. 8039 - 8042 (2015/02/02)

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.
