Check Digit Verification of cas no

The CAS Registry Mumber 51531-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,5,3 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 51531-89:
(7*5)+(6*1)+(5*5)+(4*3)+(3*1)+(2*8)+(1*9)=106
106 % 10 = 6
So 51531-89-6 is a valid CAS Registry Number.
