Check Digit Verification of cas no
The CAS Registry Mumber 148-25-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,4 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 148-25:
(5*1)+(4*4)+(3*8)+(2*2)+(1*5)=54
54 % 10 = 4
So 148-25-4 is a valid CAS Registry Number.

experimental part, p. 4072 - 4078 (2012/01/13)
A novel kinetic spectrophotometric method for the determination of protein is based on the inhibitive effect of bovine serum albumin (BSA) on the oxidation reaction of dibromo-p-sulfonic acid arsenazo (DBS-ASA) by potassium periodate in the medium of CH2ClCOOHCH3COONH4. The maximum absorption peak of BSA-(DBS-ASA)-KIO4 system is located at 530 nm. The absorbance difference (δA) is well linearly related with the concentration of bovine serum albumin over the rage of 2.5-90.0 μg/mL of solution and fitted the equation: δA = 0.01091C + 0.0646 (C: μg/mL), with a correlation coefficient γ = 0.9941. The detection limit of the method was 0.48 μg/mL. The method has been successfully used in the determination of the total content of protein in egg white and the relative standard deviation of 15 determinations were less than 5 %. The recovery of standard addition of the method was over the range of 100.1-101.2 %.
