Check Digit Verification of cas no

The CAS Registry Mumber 807331-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,7,3,3 and 1 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 807331-67:
(8*8)+(7*0)+(6*7)+(5*3)+(4*3)+(3*1)+(2*6)+(1*7)=155
155 % 10 = 5
So 807331-67-5 is a valid CAS Registry Number.
