Check Digit Verification of cas no

The CAS Registry Mumber 19438-64-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,3 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 19438-64:
(7*1)+(6*9)+(5*4)+(4*3)+(3*8)+(2*6)+(1*4)=133
133 % 10 = 3
So 19438-64-3 is a valid CAS Registry Number.

Ionic liquid, preparation method and application

-

Paragraph 0230; 0231; 0232; 0233; 0234, (2018/03/28)

The invention relates to an ionic liquid. Cations of the ionic liquid contain hexafluoroisopropyl sulfonic acid groups. According to the ionic liquid provided by the invention, the hexafluoroisopropylsulfonic acid groups are introduced into the cation part of the ionic liquid to give a super acid center to the ionic liquid, through changing anion types, the ionic liquid of which the acidity is greater than that of 98% concentrated sulfuric acid is obtained, and the highest level of the hamlet acidity (H0) in the obtained ionic liquid can reach -14.13.
