Check Digit Verification of cas no

The CAS Registry Mumber 178616-59-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,8,6,1 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 178616-59:
(8*1)+(7*7)+(6*8)+(5*6)+(4*1)+(3*6)+(2*5)+(1*9)=176
176 % 10 = 6
So 178616-59-6 is a valid CAS Registry Number.
