The CAS Registry Mumber 139926-21-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,9,2 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139926-21:
(8*1)+(7*3)+(6*9)+(5*9)+(4*2)+(3*6)+(2*2)+(1*1)=159
159 % 10 = 9
So 139926-21-9 is a valid CAS Registry Number.

Synthesis and preliminary pharmacological study of thiophene analogues of the antipyretic and analgesic agent ethenzamide

Darias,Bravo,Abdallah,Sanchez Mateo,Exposito-Orta

, p. 83 - 87 (2007/10/02)

A preliminary pharmacologcal study of a thiophene analogue 1b of the analgesic and antipyretic agent Ethenzamide and of a closely related compound 1a showed that a great similarity exists among Ethenzamide and the thiophenic compounds for analgesic, antipyretic, ulcerogenic, hypothermic, and sedative effects. However, the acute toxicity in mice for the thiophenic compounds is notably higher than that of Ethenzamide.
