Check Digit Verification of cas no

The CAS Registry Mumber 40291-26-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,2,9 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40291-26:
(7*4)+(6*0)+(5*2)+(4*9)+(3*1)+(2*2)+(1*6)=87
87 % 10 = 7
So 40291-26-7 is a valid CAS Registry Number.
