Check Digit Verification of cas no

The CAS Registry Mumber 131920-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,9,2 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 131920-31:
(8*1)+(7*3)+(6*1)+(5*9)+(4*2)+(3*0)+(2*3)+(1*1)=95
95 % 10 = 5
So 131920-31-5 is a valid CAS Registry Number.
