Check Digit Verification of cas no

The CAS Registry Mumber 18925-72-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,2 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18925-72:
(7*1)+(6*8)+(5*9)+(4*2)+(3*5)+(2*7)+(1*2)=139
139 % 10 = 9
So 18925-72-9 is a valid CAS Registry Number.
