Check Digit Verification of cas no

The CAS Registry Mumber 186522-64-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,5,2 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 186522-64:
(8*1)+(7*8)+(6*6)+(5*5)+(4*2)+(3*2)+(2*6)+(1*4)=155
155 % 10 = 5
So 186522-64-5 is a valid CAS Registry Number.
