Check Digit Verification of cas no

The CAS Registry Mumber 200190-84-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,1,9 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 200190-84:
(8*2)+(7*0)+(6*0)+(5*1)+(4*9)+(3*0)+(2*8)+(1*4)=77
77 % 10 = 7
So 200190-84-7 is a valid CAS Registry Number.
