74571-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74571-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,7 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74571-92:
(7*7)+(6*4)+(5*5)+(4*7)+(3*1)+(2*9)+(1*2)=149
149 % 10 = 9
So 74571-92-9 is a valid CAS Registry Number.

MECHANISM OF THE ETHERIFICATION OF 2-ALKYLAMINO-1-PHENYLETHANOL DERIVATIVES
Venter, D. P.,Greeff, D. F.
, p. 305 - 307 (2007/10/02)
Derivatives of 2-alkylamino-1-(4-hydroxyphenyl)-1-ethanol have been converted to the β-methylethers in good yield.Etherification of 2-alkylamino-1-(4-methoxyphenyl)-1-ethanol could not be accomplished.Based on this unreactivity, a mechanism is proposed wh
