7781-49-9 Usage
Purification Methods
Dissolve it in boiling dioxane (20g in 300mL), add H2O (100mL) slowly, cool, filter and dry it in vacuo at 100o. Its solubility in CHCl3 is ~1%. [UV: Fox & Atkinson J Am Chem Soc 72 3629 1950, Beilstein 26 III/IV 1776.]
Check Digit Verification of cas no
The CAS Registry Mumber 7781-49-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,8 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7781-49:
(6*7)+(5*7)+(4*8)+(3*1)+(2*4)+(1*9)=129
129 % 10 = 9
So 7781-49-9 is a valid CAS Registry Number.
