Check Digit Verification of cas no

The CAS Registry Mumber 28557-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,5,5 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28557-27:
(7*2)+(6*8)+(5*5)+(4*5)+(3*7)+(2*2)+(1*7)=139
139 % 10 = 9
So 28557-27-9 is a valid CAS Registry Number.
