Check Digit Verification of cas no

The CAS Registry Mumber 98187-15-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,8 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98187-15:
(7*9)+(6*8)+(5*1)+(4*8)+(3*7)+(2*1)+(1*5)=176
176 % 10 = 6
So 98187-15-6 is a valid CAS Registry Number.
