Check Digit Verification of cas no

The CAS Registry Mumber 55243-92-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,2,4 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55243-92:
(7*5)+(6*5)+(5*2)+(4*4)+(3*3)+(2*9)+(1*2)=120
120 % 10 = 0
So 55243-92-0 is a valid CAS Registry Number.
