Check Digit Verification of cas no

The CAS Registry Mumber 87572-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,5,7 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87572-47:
(7*8)+(6*7)+(5*5)+(4*7)+(3*2)+(2*4)+(1*7)=172
172 % 10 = 2
So 87572-47-2 is a valid CAS Registry Number.

Angiotensin Converting Enzyme Inhibitors: Spirapril and Related Compounds

Smith, Elizabeth M.,Swiss, Gerald F.,Neustadt, Bernard R.,McNamara, Paul,Gold, Elijah H.,et al.

, p. 1600 - 1606 (2007/10/02)

The synthesis of spirapril (5), spiraprilat (25), their RSS stereoisomers, and their glycyl (18b) and lysyl (36, 37) analogues is described.These compounds were evaluated in vivo for inhibition of angiotensin converting enzyme (ACE), and selected compounds were evaluated for in vitro ACE inhibition (spirapril ID50 16 μg/kg; spiraprilat IC50 0.8 nM, ID50 8 μg/kg).In anesthetized rats, iv, esters 5 and 36 are more potent than enalapril, and diacids 25 and 37 are more potent than enalaprilat in vitro.In the conscious rats, orally, 5 and enalapril (2) showed potent and sustained activity at doses of 0.03-1 and 0.1-1 mg/kg, respectively.From this work, spirapril was selected for clinical evaluation as an antihypertensive agent.
