Check Digit Verification of cas no

The CAS Registry Mumber 83540-99-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,4 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 83540-99:
(7*8)+(6*3)+(5*5)+(4*4)+(3*0)+(2*9)+(1*9)=142
142 % 10 = 2
So 83540-99-2 is a valid CAS Registry Number.
