Check Digit Verification of cas no

The CAS Registry Mumber 9079-34-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,7 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 9079-34:
(6*9)+(5*0)+(4*7)+(3*9)+(2*3)+(1*4)=119
119 % 10 = 9
So 9079-34-9 is a valid CAS Registry Number.
