Check Digit Verification of cas no

The CAS Registry Mumber 400751-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,7,5 and 1 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 400751-70:
(8*4)+(7*0)+(6*0)+(5*7)+(4*5)+(3*1)+(2*7)+(1*0)=104
104 % 10 = 4
So 400751-70-4 is a valid CAS Registry Number.
