Check Digit Verification of cas no
The CAS Registry Mumber 5211-44-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,1 and 1 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5211-44:
(6*5)+(5*2)+(4*1)+(3*1)+(2*4)+(1*4)=59
59 % 10 = 9
So 5211-44-9 is a valid CAS Registry Number.

A new method of measurement of thiol concentration by 19F NMR spectroscopy is developed. The method is based on the detection of products of the exchange reaction of thiols with a newly synthesized fluorinated disulfide, 2,3,5,6-tetrafluoro-4-mercaptobenzoic acid (BSSB). A significant broadening of the 19F NMR signal of BSSB in the presence of thiols was observed and attributed to the exchange reaction between the parent disulfide and 2,3,5,6-tetrafluoro-4-mercaptobenzoic acid. The rate constant for this reaction was found to be equal to (63 ± 11) × 103 M-1 s-1 at pH 7.0. The method was applied for the measurement of concentration of glutathione and albumin in rat blood.
