Check Digit Verification of cas no

The CAS Registry Mumber 87417-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,4,1 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 87417-26:
(7*8)+(6*7)+(5*4)+(4*1)+(3*7)+(2*2)+(1*6)=153
153 % 10 = 3
So 87417-26-3 is a valid CAS Registry Number.
