Check Digit Verification of cas no

The CAS Registry Mumber 84839-34-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,8,3 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 84839-34:
(7*8)+(6*4)+(5*8)+(4*3)+(3*9)+(2*3)+(1*4)=169
169 % 10 = 9
So 84839-34-9 is a valid CAS Registry Number.
