Check Digit Verification of cas no

The CAS Registry Mumber 289-13-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,8 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 289-13:
(5*2)+(4*8)+(3*9)+(2*1)+(1*3)=74
74 % 10 = 4
So 289-13-4 is a valid CAS Registry Number.
