Check Digit Verification of cas no

The CAS Registry Mumber 15402-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,4,0 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15402-26:
(7*1)+(6*5)+(5*4)+(4*0)+(3*2)+(2*2)+(1*6)=73
73 % 10 = 3
So 15402-26-3 is a valid CAS Registry Number.
