Check Digit Verification of cas no

The CAS Registry Mumber 188957-17-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,9,5 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 188957-17:
(8*1)+(7*8)+(6*8)+(5*9)+(4*5)+(3*7)+(2*1)+(1*7)=207
207 % 10 = 7
So 188957-17-7 is a valid CAS Registry Number.
