Check Digit Verification of cas no

The CAS Registry Mumber 68494-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,4,9 and 4 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68494-09:
(7*6)+(6*8)+(5*4)+(4*9)+(3*4)+(2*0)+(1*9)=167
167 % 10 = 7
So 68494-09-7 is a valid CAS Registry Number.
