Check Digit Verification of cas no

The CAS Registry Mumber 304675-74-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,6,7 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 304675-74:
(8*3)+(7*0)+(6*4)+(5*6)+(4*7)+(3*5)+(2*7)+(1*4)=139
139 % 10 = 9
So 304675-74-9 is a valid CAS Registry Number.
