Check Digit Verification of cas no

The CAS Registry Mumber 172605-83-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,6,0 and 5 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 172605-83:
(8*1)+(7*7)+(6*2)+(5*6)+(4*0)+(3*5)+(2*8)+(1*3)=133
133 % 10 = 3
So 172605-83-3 is a valid CAS Registry Number.
