Check Digit Verification of cas no

The CAS Registry Mumber 211915-73-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,1,9,1 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 211915-73:
(8*2)+(7*1)+(6*1)+(5*9)+(4*1)+(3*5)+(2*7)+(1*3)=110
110 % 10 = 0
So 211915-73-0 is a valid CAS Registry Number.

Disubstituted bicyclic heterocycles, the preparations and the use thereof as pharmaceutical compositions

-

, (2008/06/13)

New disubstituted bicyclic heterocycles of general formula Ra-A-Het-B-Ar-E (I)Compounds of the above general formula I, wherein E denotes an RbNH-C(=NH)- group, have valuable pharmacological properties, particularly a thrombin-inhibiting effect and the effect of prolonging thrombin time, and those wherein E denotes a cyano group, are valuable intermediates for preparing the other compounds of general formula I. Exemplary compounds of formula I are: (a) 1-Methyl-2-[N-(4-amidinophenyl)-aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-phenyl-N-(2-hydroxycarbonylethyl)-amide, (b) 1-Methyl-2-[N-(4-amidinophenyl)-aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-(2-pyridyl)-N-(hydroxycarbonylmethyl)-amide, (c) 1-Methyl-2-[N-(4-amidino-2-methoxy-phenyl)-aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-(2-pyridyl)-N-(hydroxycarbonylmethyl)-amide, and (d) 1-Methyl-2-[N-[4-(N-n-hexyloxycarbonylamidino)phenyl]aminomethyl]-benzimidazol-5-yl-carboxylic acid-N-(2-pyridyl)-N-(2-ethoxycarbonylethyl) amide.
