28267-53-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28267-53-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,6 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28267-53:
(7*2)+(6*8)+(5*2)+(4*6)+(3*7)+(2*5)+(1*3)=130
130 % 10 = 0
So 28267-53-0 is a valid CAS Registry Number.
