Check Digit Verification of cas no
The CAS Registry Mumber 1763-23-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1763-23:
(6*1)+(5*7)+(4*6)+(3*3)+(2*2)+(1*3)=81
81 % 10 = 1
So 1763-23-1 is a valid CAS Registry Number.

This study describes a synthesis of symmetric and dissymmetric bis[(perfluoroalkane)-sulfonyl]imides by the reaction of the sodium salt of perfluoroalkanesulfonamide RFSO2NH-Na + (RF = C4F9, C6F 13, C8F17) with hexamethyldisilazane and perfluoroalkanesulfonylfluoride RFSO2F (RF - C4F9, C6F13, C8F 17). They are obtained, in two steps, in moderate overall yield. Moreover, this paper provides a study of their inhibition on bovine carbonic anhydrase.
