Definition
potassium sulphite: A white crystallinesolid, K2SO3, soluble in waterand very sparingly soluble inethanol; r.d. 1.51; decomposes onheating. It is a reducing agent and isused as such in photography and inthe food and brewing industries,where it prevents oxidation.
Safety Profile
When heated to
decomposition it emits toxic fumes of SOx
and K2O. See also SULFUROUS ACID and
SULFITES.
Check Digit Verification of cas no
The CAS Registry Mumber 10117-38-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,1,1 and 7 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10117-38:
(7*1)+(6*0)+(5*1)+(4*1)+(3*7)+(2*3)+(1*8)=51
51 % 10 = 1
So 10117-38-1 is a valid CAS Registry Number.
