Check Digit Verification of cas no

The CAS Registry Mumber 57904-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,0 and 4 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 57904-90:
(7*5)+(6*7)+(5*9)+(4*0)+(3*4)+(2*9)+(1*0)=152
152 % 10 = 2
So 57904-90-2 is a valid CAS Registry Number.
