Check Digit Verification of cas no

The CAS Registry Mumber 53997-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,9,9 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 53997-64:
(7*5)+(6*3)+(5*9)+(4*9)+(3*7)+(2*6)+(1*4)=171
171 % 10 = 1
So 53997-64-1 is a valid CAS Registry Number.

Practical preparation of potentially anesthetic fluorinated ethyl methyl ethers by means of bromine trifluoride and other methods

Hudlicky, Tomas,Duan, Caiming,Reed, Josephine W.,Yan, Fengyang,Hudlicky, Milos,Endoma, Mary Ann,Eger II, Edmond I.

, p. 363 - 367 (2007/10/03)

Synthetic methods, especially those that use bromine trifluoride as a fluorinating agent, are described for the preparation of a number of fluorinated ethyl methyl ethers in good yield and high purity. In all cases, medium-scale syntheses (8-22g) of potentially anesthetic compounds have been accomplished. The compounds are of sufficient purity (>99%) for biological evaluation.
