Check Digit Verification of cas no

The CAS Registry Mumber 178761-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,7,6 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 178761-52:
(8*1)+(7*7)+(6*8)+(5*7)+(4*6)+(3*1)+(2*5)+(1*2)=179
179 % 10 = 9
So 178761-52-9 is a valid CAS Registry Number.
