Check Digit Verification of cas no

The CAS Registry Mumber 1398511-80-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,8,5,1 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1398511-80:
(9*1)+(8*3)+(7*9)+(6*8)+(5*5)+(4*1)+(3*1)+(2*8)+(1*0)=192
192 % 10 = 2
So 1398511-80-2 is a valid CAS Registry Number.
