Check Digit Verification of cas no

The CAS Registry Mumber 83816-91-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,8,1 and 6 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83816-91:
(7*8)+(6*3)+(5*8)+(4*1)+(3*6)+(2*9)+(1*1)=155
155 % 10 = 5
So 83816-91-5 is a valid CAS Registry Number.
