Check Digit Verification of cas no

The CAS Registry Mumber 7499-62-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,9 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7499-62:
(6*7)+(5*4)+(4*9)+(3*9)+(2*6)+(1*2)=139
139 % 10 = 9
So 7499-62-9 is a valid CAS Registry Number.
