813439-55-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 813439-55-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,1,3,4,3 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 813439-55:
(8*8)+(7*1)+(6*3)+(5*4)+(4*3)+(3*9)+(2*5)+(1*5)=163
163 % 10 = 3
So 813439-55-3 is a valid CAS Registry Number.
