Check Digit Verification of cas no

The CAS Registry Mumber 138785-13-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,8 and 5 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138785-13:
(8*1)+(7*3)+(6*8)+(5*7)+(4*8)+(3*5)+(2*1)+(1*3)=164
164 % 10 = 4
So 138785-13-4 is a valid CAS Registry Number.
