Check Digit Verification of cas no

The CAS Registry Mumber 135993-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,9 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 135993-75:
(8*1)+(7*3)+(6*5)+(5*9)+(4*9)+(3*3)+(2*7)+(1*5)=168
168 % 10 = 8
So 135993-75-8 is a valid CAS Registry Number.
