Check Digit Verification of cas no

The CAS Registry Mumber 84283-70-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,2,8 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 84283-70:
(7*8)+(6*4)+(5*2)+(4*8)+(3*3)+(2*7)+(1*0)=145
145 % 10 = 5
So 84283-70-5 is a valid CAS Registry Number.
