Check Digit Verification of cas no

The CAS Registry Mumber 90013-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,1 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90013-25:
(7*9)+(6*0)+(5*0)+(4*1)+(3*3)+(2*2)+(1*5)=85
85 % 10 = 5
So 90013-25-5 is a valid CAS Registry Number.
