5000-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5000-40-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,0 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5000-40:
(6*5)+(5*0)+(4*0)+(3*0)+(2*4)+(1*0)=38
38 % 10 = 8
So 5000-40-8 is a valid CAS Registry Number.

, p. 1199 - 1203 (2015)
The reaction between sulfur(IV) oxide and aqueous methylamine yields "onium" sulfate (CH3NH3)2SO4, which was characterized by X-ray diffraction, IR spectroscopy, and mass spectrometry. The structure of the sulfate is stabilized by a network of NH...O hydrogen bonds.
