19046-87-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19046-87-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,4 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19046-87:
(7*1)+(6*9)+(5*0)+(4*4)+(3*6)+(2*8)+(1*7)=118
118 % 10 = 8
So 19046-87-8 is a valid CAS Registry Number.

Absolute pKas of Sulfonamides in Ionic Liquids: Comparisons to Molecular Solvents
Wang, Zedong,Li, Xin,Ji, Pengju,Cheng, Jin-Pei
, p. 11195 - 11200 (2016)
Absolute pKas of 25 sulfonamides in four ionic liquids (ILs) were measured spectroscopically with high precision and subsequently compared with those in conventional molecular solvents. It is found that the acidity order of these sulfonamides i
