Check Digit Verification of cas no

The CAS Registry Mumber 131380-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,3,8 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131380-01:
(8*1)+(7*3)+(6*1)+(5*3)+(4*8)+(3*0)+(2*0)+(1*1)=83
83 % 10 = 3
So 131380-01-3 is a valid CAS Registry Number.
