Check Digit Verification of cas no

The CAS Registry Mumber 18427-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,2 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 18427-47:
(7*1)+(6*8)+(5*4)+(4*2)+(3*7)+(2*4)+(1*7)=119
119 % 10 = 9
So 18427-47-9 is a valid CAS Registry Number.
