Check Digit Verification of cas no

The CAS Registry Mumber 90813-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,1 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90813-40:
(7*9)+(6*0)+(5*8)+(4*1)+(3*3)+(2*4)+(1*0)=124
124 % 10 = 4
So 90813-40-4 is a valid CAS Registry Number.
