Check Digit Verification of cas no

The CAS Registry Mumber 138875-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,7 and 5 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138875-75:
(8*1)+(7*3)+(6*8)+(5*8)+(4*7)+(3*5)+(2*7)+(1*5)=179
179 % 10 = 9
So 138875-75-9 is a valid CAS Registry Number.
