Check Digit Verification of cas no

The CAS Registry Mumber 55747-48-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,4 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55747-48:
(7*5)+(6*5)+(5*7)+(4*4)+(3*7)+(2*4)+(1*8)=153
153 % 10 = 3
So 55747-48-3 is a valid CAS Registry Number.
