Check Digit Verification of cas no

The CAS Registry Mumber 117531-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,3 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 117531-99:
(8*1)+(7*1)+(6*7)+(5*5)+(4*3)+(3*1)+(2*9)+(1*9)=124
124 % 10 = 4
So 117531-99-4 is a valid CAS Registry Number.
