Check Digit Verification of cas no

The CAS Registry Mumber 874583-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,4,5,8 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 874583-48:
(8*8)+(7*7)+(6*4)+(5*5)+(4*8)+(3*3)+(2*4)+(1*8)=219
219 % 10 = 9
So 874583-48-9 is a valid CAS Registry Number.
