Check Digit Verification of cas no

The CAS Registry Mumber 81156-62-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,5 and 6 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81156-62:
(7*8)+(6*1)+(5*1)+(4*5)+(3*6)+(2*6)+(1*2)=119
119 % 10 = 9
So 81156-62-9 is a valid CAS Registry Number.
