Check Digit Verification of cas no

The CAS Registry Mumber 138588-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,5,8 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138588-05:
(8*1)+(7*3)+(6*8)+(5*5)+(4*8)+(3*8)+(2*0)+(1*5)=163
163 % 10 = 3
So 138588-05-3 is a valid CAS Registry Number.
