Check Digit Verification of cas no

The CAS Registry Mumber 21247-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,2,4 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21247-44:
(7*2)+(6*1)+(5*2)+(4*4)+(3*7)+(2*4)+(1*4)=79
79 % 10 = 9
So 21247-44-9 is a valid CAS Registry Number.
