Check Digit Verification of cas no

The CAS Registry Mumber 849920-06-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,9,2 and 0 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 849920-06:
(8*8)+(7*4)+(6*9)+(5*9)+(4*2)+(3*0)+(2*0)+(1*6)=205
205 % 10 = 5
So 849920-06-5 is a valid CAS Registry Number.
