Check Digit Verification of cas no

The CAS Registry Mumber 74971-18-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,7 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74971-18:
(7*7)+(6*4)+(5*9)+(4*7)+(3*1)+(2*1)+(1*8)=159
159 % 10 = 9
So 74971-18-9 is a valid CAS Registry Number.
