Check Digit Verification of cas no

The CAS Registry Mumber 62639-98-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,6,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 62639-98:
(7*6)+(6*2)+(5*6)+(4*3)+(3*9)+(2*9)+(1*8)=149
149 % 10 = 9
So 62639-98-9 is a valid CAS Registry Number.
