28532-64-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28532-64-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,3 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 28532-64:
(7*2)+(6*8)+(5*5)+(4*3)+(3*2)+(2*6)+(1*4)=121
121 % 10 = 1
So 28532-64-1 is a valid CAS Registry Number.
