Uses
2-(5-Bromo-2-pyridylazo)-5-(diethylamino)phenol is used in the spectrophotometric flow injection assay for the determination of trace amount of thiocyanate level in saliva from smokers and non-smokers, also in the spectrophotometric investigation of sensitive complexing agents for the determination of zinc in serum. Dyes and metabolites.
Check Digit Verification of cas no
The CAS Registry Mumber 14337-53-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,3,3 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 14337-53:
(7*1)+(6*4)+(5*3)+(4*3)+(3*7)+(2*5)+(1*3)=92
92 % 10 = 2
So 14337-53-2 is a valid CAS Registry Number.
