Check Digit Verification of cas no

The CAS Registry Mumber 81924-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,2 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81924-49:
(7*8)+(6*1)+(5*9)+(4*2)+(3*4)+(2*4)+(1*9)=144
144 % 10 = 4
So 81924-49-4 is a valid CAS Registry Number.
