Check Digit Verification of cas no

The CAS Registry Mumber 49787-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,9,7,8 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 49787-03:
(7*4)+(6*9)+(5*7)+(4*8)+(3*7)+(2*0)+(1*3)=173
173 % 10 = 3
So 49787-03-3 is a valid CAS Registry Number.
