Check Digit Verification of cas no

The CAS Registry Mumber 121224-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,2,2 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121224-54:
(8*1)+(7*2)+(6*1)+(5*2)+(4*2)+(3*4)+(2*5)+(1*4)=72
72 % 10 = 2
So 121224-54-2 is a valid CAS Registry Number.
