5169-81-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 5169-81-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,6 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5169-81:
(6*5)+(5*1)+(4*6)+(3*9)+(2*8)+(1*1)=103
103 % 10 = 3
So 5169-81-3 is a valid CAS Registry Number.
