137864-30-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137864-30-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,6 and 4 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 137864-30:
(8*1)+(7*3)+(6*7)+(5*8)+(4*6)+(3*4)+(2*3)+(1*0)=153
153 % 10 = 3
So 137864-30-3 is a valid CAS Registry Number.

, (2008/06/13)

Compounds of the formula STR1 in which R 1 is an aliphatic hydrocarbon radical which is unsubstituted or substituted by halogen or hydroxyl, or a cycloaliphatic or araliphatic hydrocarbon radical; X 1 is CO, SO 2, or--O--C(=O)--with the carbon atom of the carbonyl group being attached to the nitrogen atom shown in formula I; X 2 is a divalent aliphatic hydrocarbon radical which is unsubstituted or substituted by hydroxyl, carboxyl, amino, guanidino or a cycloaliphatic or aromatic radical, or is a divalent cycloaliphatic hydrocarbon radical, it being possible for a carbon atom of the aliphatic hydrocarbon radical to be additionally bridged by a divalent aliphatic hydrocarbon radical; R. sub.2 is carboxyl which, if desired, is esterified or amidated, substituted or unsubstituted amino, formyl which, if desired, is acetalized, 1H-tetrazol-5-yl, pyridyl, hydroxyl which, if desired, is etherified, S(O) m--R where m is 0, 1 or 2 and R is hydrogen or an aliphatic hydrocarbon radical, alkanoyl, unsubstituted or N-substituted sulfamoyl or PO n H 2 where n is 2 or 3; X 3 is a divalent aliphatic hydrocarbon; R 3 is carboxyl, 5-tetrazolyl, SO. sub.3 H, PO. sub.2 H 2, PO 3 H 2 or haloalkylsulfamoyl; and the rings A and B independently of one another are substituted or unsubstituted; in free form or in salt form, can be prepared in a manner known per se and can be used, for example, as medicament active ingredients.
