Check Digit Verification of cas no

The CAS Registry Mumber 136621-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,6,2 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136621-89:
(8*1)+(7*3)+(6*6)+(5*6)+(4*2)+(3*1)+(2*8)+(1*9)=131
131 % 10 = 1
So 136621-89-1 is a valid CAS Registry Number.

Antiulcer agents. II. Synthesis and gastric acid antisecretory activity of N-[3-{3-(piperidinomethyl)phenoxy}propyl]-4-(1-methyl-1H-tetrazol-5- ylthio)butanamide and related compound

Ueda,Ishii,Sinozaki,Seiki,Hatanaka

, p. 1430 - 1435 (2007/10/02)

N-[3-{3-(Piperidinomethyl)phenoxy}propyl]butamides having a 1-methyl-1H-tetrazol-5-ylthio moiety as a pharmacophore and related compounds were prepared and tested for their antisecretory activity against histamine-induced gastric acid secretion in conscious rats with gastric fistulas. Most of the compounds showed antisecretory activity. Among them, N-[3-{3-(piperidinomethyl)phenoxy}propyl]-4-(1-methyl-1H-tetrazol-5- ylthio)butanamide (5f) was found to possess the most potent activity, and a possibility of isosteric replacement of the methoxycarbonyl group with 1-methyl-1H-tetrazol-5-yl group was indicated. The structure-activity relationships are also discussed.
