Check Digit Verification of cas no

The CAS Registry Mumber 81620-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,2 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81620-75:
(7*8)+(6*1)+(5*6)+(4*2)+(3*0)+(2*7)+(1*5)=119
119 % 10 = 9
So 81620-75-9 is a valid CAS Registry Number.
