Check Digit Verification of cas no

The CAS Registry Mumber 90047-42-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,4 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90047-42:
(7*9)+(6*0)+(5*0)+(4*4)+(3*7)+(2*4)+(1*2)=110
110 % 10 = 0
So 90047-42-0 is a valid CAS Registry Number.
