Check Digit Verification of cas no

The CAS Registry Mumber 138059-59-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,5 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138059-59:
(8*1)+(7*3)+(6*8)+(5*0)+(4*5)+(3*9)+(2*5)+(1*9)=143
143 % 10 = 3
So 138059-59-3 is a valid CAS Registry Number.
