Chemical Properties
Hafnium borohydride is the most volatile hafnium compound (mp 29℃, bp 118℃). It is prepared by reacting sodium fluorohafniate with aluminum borohydride for several days at room temperature, followed by distillation of the hafnium borohydride by fractionation to separate it from the aluminum borohydride.Check Digit Verification of cas no
The CAS Registry Mumber 25869-93-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,8,6 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.Calculate Digit Verification of CAS Registry Number 25869-93:
(7*2)+(6*5)+(5*8)+(4*6)+(3*9)+(2*9)+(1*3)=156
156 % 10 = 6
So 25869-93-6 is a valid CAS Registry Number.
