Check Digit Verification of cas no

The CAS Registry Mumber 104040-75-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,0,4 and 0 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104040-75:
(8*1)+(7*0)+(6*4)+(5*0)+(4*4)+(3*0)+(2*7)+(1*5)=67
67 % 10 = 7
So 104040-75-7 is a valid CAS Registry Number.
