Check Digit Verification of cas no

The CAS Registry Mumber 19825-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,2 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19825-55:
(7*1)+(6*9)+(5*8)+(4*2)+(3*5)+(2*5)+(1*5)=139
139 % 10 = 9
So 19825-55-9 is a valid CAS Registry Number.
