Check Digit Verification of cas no

The CAS Registry Mumber 87409-78-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,0 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 87409-78:
(7*8)+(6*7)+(5*4)+(4*0)+(3*9)+(2*7)+(1*8)=167
167 % 10 = 7
So 87409-78-7 is a valid CAS Registry Number.
