Check Digit Verification of cas no

The CAS Registry Mumber 133816-24-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,8,1 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 133816-24:
(8*1)+(7*3)+(6*3)+(5*8)+(4*1)+(3*6)+(2*2)+(1*4)=117
117 % 10 = 7
So 133816-24-7 is a valid CAS Registry Number.
