Check Digit Verification of cas no

The CAS Registry Mumber 57954-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,9,5 and 4 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57954-84:
(7*5)+(6*7)+(5*9)+(4*5)+(3*4)+(2*8)+(1*4)=174
174 % 10 = 4
So 57954-84-4 is a valid CAS Registry Number.
