Preparation
Barium phosphite is soluble in water so that a vacuum
evaporation is needed to form the hemihydrate, Ba(H2-
PO3)2·0.5H2O. It can also be prepared by the action of
ammonium phosphite on barium chloride:
BaCl2 (aq) + 2NH4HPO3 (aq) ? Ba(H2PO3)2·0.5H2O
+ 2NH4Cl (aq).
Check Digit Verification of cas no
The CAS Registry Mumber 26946-37-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,4 and 6 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26946-37:
(7*2)+(6*6)+(5*9)+(4*4)+(3*6)+(2*3)+(1*7)=142
142 % 10 = 2
So 26946-37-2 is a valid CAS Registry Number.
