Check Digit Verification of cas no

The CAS Registry Mumber 138355-80-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,5 and 5 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 138355-80:
(8*1)+(7*3)+(6*8)+(5*3)+(4*5)+(3*5)+(2*8)+(1*0)=143
143 % 10 = 3
So 138355-80-3 is a valid CAS Registry Number.
