Check Digit Verification of cas no

The CAS Registry Mumber 99142-43-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,1,4 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99142-43:
(7*9)+(6*9)+(5*1)+(4*4)+(3*2)+(2*4)+(1*3)=155
155 % 10 = 5
So 99142-43-5 is a valid CAS Registry Number.
