Check Digit Verification of cas no

The CAS Registry Mumber 7084-12-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,8 and 4 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7084-12:
(6*7)+(5*0)+(4*8)+(3*4)+(2*1)+(1*2)=90
90 % 10 = 0
So 7084-12-0 is a valid CAS Registry Number.
