Check Digit Verification of cas no

The CAS Registry Mumber 57138-54-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,1,3 and 8 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 57138-54:
(7*5)+(6*7)+(5*1)+(4*3)+(3*8)+(2*5)+(1*4)=132
132 % 10 = 2
So 57138-54-2 is a valid CAS Registry Number.
