Check Digit Verification of cas no

The CAS Registry Mumber 98754-22-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,5 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98754-22:
(7*9)+(6*8)+(5*7)+(4*5)+(3*4)+(2*2)+(1*2)=184
184 % 10 = 4
So 98754-22-4 is a valid CAS Registry Number.

, p. 1116 - 1128 (2007/10/02)

A series of 1- and 3-(1-substituted 4-piperidinyl)-1,2,3,4-tetrahydro-2-oxoquinazolines were synthesized and tested for antihypertensive activity. Among the compounds tested, 1-(2-hydroxy-2-phenethyl)-4-(1,2,3,4-tetrahydro-2-oxo-3-quinazolinyl) piperidine derivatives were generally the most effective in lowering blood pressure in the spontaneous hypertensive rat model. Of these, 1-[2-(4-chlorophenyl)-2-hydroxyethyl]-4-(1,2,3,4-tetrahydro-2-oxo-3- quinazolinyl)piperidine (KF5908) seemed the most promising.
