Check Digit Verification of cas no

The CAS Registry Mumber 1448-61-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1448-61:
(6*1)+(5*4)+(4*4)+(3*8)+(2*6)+(1*1)=79
79 % 10 = 9
So 1448-61-9 is a valid CAS Registry Number.
