70977-75-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 70977-75-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,9,7 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 70977-75:
(7*7)+(6*0)+(5*9)+(4*7)+(3*7)+(2*7)+(1*5)=162
162 % 10 = 2
So 70977-75-2 is a valid CAS Registry Number.

-

, (2008/06/13)

New tetrazole derivatives of the general formula: STR1 [wherein R1 represents a halogen atom, a straight- or branched-chain alkyl, alkoxy, alkylthio, alkylsulphinyl, alkylsulphonyl or alkylsulphamoyl group, each such group containing from 1 to 6 carbon atoms, a dialkylsulphamoyl, dialkylamino, or dialkylcarbamoyl group (wherein the two alkyl groups may be the same or different and each contains from 1 to 4 carbon atoms), a straight- or branched-chain alkanoyl, alkoxycarbonyl, alkoxycarbonylamino, alkylcarbamoyl or alkanoylamino group containing from 2 to 6 carbon atoms, a cycloalkylcarbonyl group containing from 3 to 8 carbon atoms in the cycloalkyl moiety, or a hydroxy, formyl, nitro, trifluoromethyl, trifluoroacetyl, aryl, benzyloxycarbonylamino, amino, sulphamoyl, cyano, tetrazol-5-yl, carboxy, carbamoyl, benzyloxy, aralkanoyl or aroyl group, or a group of the formula: (wherein R2 represents a hydrogen atom or a straight- or branched-chain alkyl group containing from 1 to 5 carbon atoms, an aryl, aralkyl or trifluoromethyl group, or a cycloalkyl group containing from 3 to 8 carbon atoms, and R3 represents a hydrogen atom, or a straight- or branched-chain alkyl group containing from 1 to 6 carbon atoms optionally substituted by a phenyl group, or represents an aryl group optionally substituted by one or more substituents selected from halogen atoms and straight- or branched-chain alkyl and alkoxy groups containing from 1 to 6 carbon atoms and hydroxy, trifluoromethyl and nitro groups), and m represents zero or an integer 1, 2 or 3, the substituents R1 being the same or different when m represents 2 or 3] possess pharmacological properties, in particular properties of value in the treatment of allergic conditions.
