Check Digit Verification of cas no

The CAS Registry Mumber 735226-77-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,5,2,2 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 735226-77:
(8*7)+(7*3)+(6*5)+(5*2)+(4*2)+(3*6)+(2*7)+(1*7)=164
164 % 10 = 4
So 735226-77-4 is a valid CAS Registry Number.

Synthesis and antihypertensive activity of a series of 4-amino-6,7-dimethoxyquinazoline derivatives

Manoury,Binet,Dumas,Lefevre-Borg,Cavero

, p. 19 - 25 (2007/10/02)

A series of N2-[(acylamino)alkyl]-6,7-dimethoxy-2,4-quinazolinediamines was synthesized as potential α1-adrenoceptor antagonists. When administered to spontaneously hypertensive rats at 10 mg/kg po, a number of propanediamine derivatives showed good antihypertensive activity, whereas the ethanediamine derivatives, albeit being structurally more closely related to prazosin, were devoid of this property. The most active derivative, N-[3-[(4-amino-6,7-dimethoxy-2-quinazolinyl)methylamino]propyl]tetrahydro- 2-furancarboxamide hydrochloride, alfuzosin, showed high selectivity for peripheral α1-postjunctional adrenoceptors. At equiactive antihypertensive doses, its effect on the pressor response to postural changes in conscious dog was less marked than that shown by prazosin. In the light of these results, alfuzosin was selected for clinical evaluation.
