Check Digit Verification of cas no

The CAS Registry Mumber 7293-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,9 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7293-78:
(6*7)+(5*2)+(4*9)+(3*3)+(2*7)+(1*8)=119
119 % 10 = 9
So 7293-78-9 is a valid CAS Registry Number.
