53731-89-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 53731-89-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,7,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 53731-89:
(7*5)+(6*3)+(5*7)+(4*3)+(3*1)+(2*8)+(1*9)=128
128 % 10 = 8
So 53731-89-8 is a valid CAS Registry Number.
