Check Digit Verification of cas no

The CAS Registry Mumber 67421-54-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,2 and 1 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67421-54:
(7*6)+(6*7)+(5*4)+(4*2)+(3*1)+(2*5)+(1*4)=129
129 % 10 = 9
So 67421-54-9 is a valid CAS Registry Number.
