Check Digit Verification of cas no

The CAS Registry Mumber 303153-90-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,5 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 303153-90:
(8*3)+(7*0)+(6*3)+(5*1)+(4*5)+(3*3)+(2*9)+(1*0)=94
94 % 10 = 4
So 303153-90-4 is a valid CAS Registry Number.
