Check Digit Verification of cas no

The CAS Registry Mumber 158751-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,7,5 and 1 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158751-55:
(8*1)+(7*5)+(6*8)+(5*7)+(4*5)+(3*1)+(2*5)+(1*5)=164
164 % 10 = 4
So 158751-55-4 is a valid CAS Registry Number.

Substituted benzenesulfonylureas and thioureas-process for their preparation and their use as pharmaceuticals

-

Example 1, (2010/01/30)

Benzenesulfonylureas and -thioureas of the formula I where R(1) in N or (fluoro)methyl, R(2) is H, Hal or (fluoro)(mercapto)alk(oxy)yl, E is O or S, Y is —[CR(3)2]n—, where R(3)=H or alkyl and n=1-4, X is H, Hal or alkyl and Z is Hal, NO2or alk(yl)oxy, are described. The compounds I are used for treatment of disturbances in cardiac rhythm and prevention of sudden cardiac death caused by arrhythmia, and can therefore be used as antiarrhythmics. They are particularly suitable for those cases where arrhythmias are a consequence of a narrowing of a coronary vessel, such as angina pectoris or acute cardiac infarction.
