Check Digit Verification of cas no

The CAS Registry Mumber 90404-57-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,4,0 and 4 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90404-57:
(7*9)+(6*0)+(5*4)+(4*0)+(3*4)+(2*5)+(1*7)=112
112 % 10 = 2
So 90404-57-2 is a valid CAS Registry Number.
