Check Digit Verification of cas no

The CAS Registry Mumber 957853-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,8,5 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 957853-17:
(8*9)+(7*5)+(6*7)+(5*8)+(4*5)+(3*3)+(2*1)+(1*7)=227
227 % 10 = 7
So 957853-17-7 is a valid CAS Registry Number.
