Check Digit Verification of cas no

The CAS Registry Mumber 97760-95-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,7,6 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 97760-95:
(7*9)+(6*7)+(5*7)+(4*6)+(3*0)+(2*9)+(1*5)=187
187 % 10 = 7
So 97760-95-7 is a valid CAS Registry Number.

Synthesis of further amino-halogen-substituted phenyl-aminoethanols

Kruger,Keck,Noll,Pieper

, p. 1612 - 1624 (2007/10/02)

Starting from clenbuterol as a lead structure, new 4-amino-phenyl-aminoethanol analogues have been synthesized by different approaches. In these compounds one or both of the chlorine atoms of clenbuterol are replaced by other residues. This has led to compounds with high intrinsic β2-mimetic and/or β1-blocking activities. 1-(4-Amino-3-chloro-5-trifluoromethyl-phenyl)-2-tert.-butylamino-ethanol hydrochloride (mabuterol) has been selected for clinical development. A detailed description is also given of the syntheses of new intermediate acetophenone derivatives as well as of the resolution of mabuterol into its enantiomers.
