Check Digit Verification of cas no

The CAS Registry Mumber 130925-64-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,9,2 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 130925-64:
(8*1)+(7*3)+(6*0)+(5*9)+(4*2)+(3*5)+(2*6)+(1*4)=113
113 % 10 = 3
So 130925-64-3 is a valid CAS Registry Number.
