Check Digit Verification of cas no

The CAS Registry Mumber 172853-82-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,8,5 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 172853-82:
(8*1)+(7*7)+(6*2)+(5*8)+(4*5)+(3*3)+(2*8)+(1*2)=156
156 % 10 = 6
So 172853-82-6 is a valid CAS Registry Number.
