43077-49-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 43077-49-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,3,0,7 and 7 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 43077-49:
(7*4)+(6*3)+(5*0)+(4*7)+(3*7)+(2*4)+(1*9)=112
112 % 10 = 2
So 43077-49-2 is a valid CAS Registry Number.

, (2008/06/13)

The present invention relates to new nitrogen-containing organophosphorus compounds having aryloxy substituents bonded to phosphorus in ester structures. STR1 R' is aryl of 6 to 10 carbon atoms, R" is hydrogen, alkyl, aryl or haloaryl of 1 to 15 carbon atoms, or no more than one carboethoxymethyl group, and where the halogen on the aryl group is bromine, chlorine or fluorine, R'" is alkyl, alkenyl or aryl groups of 1 to 15 carbon atoms and substituted aryl forms where the subtituent is fluorine, chlorine, bromine, nitro, cyano, hydroxyl, alkyloxy or mixtures of such substituents, and Z is CO, CS or SO2. The phosphorus compounds have utility as fire retardants and as biologically active materials.
