Check Digit Verification of cas no

The CAS Registry Mumber 90459-20-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90459-20:
(7*9)+(6*0)+(5*4)+(4*5)+(3*9)+(2*2)+(1*0)=134
134 % 10 = 4
So 90459-20-4 is a valid CAS Registry Number.
