Check Digit Verification of cas no

The CAS Registry Mumber 24894-29-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,9 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 24894-29:
(7*2)+(6*4)+(5*8)+(4*9)+(3*4)+(2*2)+(1*9)=139
139 % 10 = 9
So 24894-29-9 is a valid CAS Registry Number.
