Check Digit Verification of cas no

The CAS Registry Mumber 34600-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,0 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34600-17:
(7*3)+(6*4)+(5*6)+(4*0)+(3*0)+(2*1)+(1*7)=84
84 % 10 = 4
So 34600-17-4 is a valid CAS Registry Number.
