Check Digit Verification of cas no

The CAS Registry Mumber 4905-71-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,0 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4905-71:
(6*4)+(5*9)+(4*0)+(3*5)+(2*7)+(1*1)=99
99 % 10 = 9
So 4905-71-9 is a valid CAS Registry Number.
