Check Digit Verification of cas no

The CAS Registry Mumber 28812-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,1 and 2 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 28812-36:
(7*2)+(6*8)+(5*8)+(4*1)+(3*2)+(2*3)+(1*6)=124
124 % 10 = 4
So 28812-36-4 is a valid CAS Registry Number.
