Check Digit Verification of cas no

The CAS Registry Mumber 134291-10-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,2,9 and 1 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 134291-10:
(8*1)+(7*3)+(6*4)+(5*2)+(4*9)+(3*1)+(2*1)+(1*0)=104
104 % 10 = 4
So 134291-10-4 is a valid CAS Registry Number.
