Check Digit Verification of cas no

The CAS Registry Mumber 173312-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,3,1 and 2 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 173312-52:
(8*1)+(7*7)+(6*3)+(5*3)+(4*1)+(3*2)+(2*5)+(1*2)=112
112 % 10 = 2
So 173312-52-2 is a valid CAS Registry Number.
