Check Digit Verification of cas no

The CAS Registry Mumber 849021-16-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,0,2 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 849021-16:
(8*8)+(7*4)+(6*9)+(5*0)+(4*2)+(3*1)+(2*1)+(1*6)=165
165 % 10 = 5
So 849021-16-5 is a valid CAS Registry Number.
