Check Digit Verification of cas no

The CAS Registry Mumber 613676-99-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,3,6,7 and 6 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 613676-99:
(8*6)+(7*1)+(6*3)+(5*6)+(4*7)+(3*6)+(2*9)+(1*9)=176
176 % 10 = 6
So 613676-99-6 is a valid CAS Registry Number.
