Check Digit Verification of cas no

The CAS Registry Mumber 7090-19-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,9 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7090-19:
(6*7)+(5*0)+(4*9)+(3*0)+(2*1)+(1*9)=89
89 % 10 = 9
So 7090-19-9 is a valid CAS Registry Number.
