Check Digit Verification of cas no

The CAS Registry Mumber 33321-56-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,3,2 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 33321-56:
(7*3)+(6*3)+(5*3)+(4*2)+(3*1)+(2*5)+(1*6)=81
81 % 10 = 1
So 33321-56-1 is a valid CAS Registry Number.

β Adrenoceptor blocking agents. I. Cardioselective 1 aryloxy 3 (aryloxyalkylamino)propan 2 ols

Augstein,Cox,Ham,Leeming,Snarey

, p. 1245 - 1251 (2007/10/05)

A series of 1 aryloxy 3 (aryloxyalkylamino)propan 2 ols was synthesized and investigated for cardioselective β adrenoceptor blocking activity. Several compounds exhibited potency comparable with that of propranolol, both in vitro and in vivo, and showed selectivity for cardiac vs. tracheal receptors. The cardiac depressant activity of the compounds was generally much less marked than that exhibited by propranolol. Tolamolol has been shown to be a cardiac selective β adrenoceptor blocking agent in man.
