Check Digit Verification of cas no

The CAS Registry Mumber 81932-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,3 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81932-09:
(7*8)+(6*1)+(5*9)+(4*3)+(3*2)+(2*0)+(1*9)=134
134 % 10 = 4
So 81932-09-4 is a valid CAS Registry Number.
