Check Digit Verification of cas no

The CAS Registry Mumber 473840-72-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,8,4 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 473840-72:
(8*4)+(7*7)+(6*3)+(5*8)+(4*4)+(3*0)+(2*7)+(1*2)=171
171 % 10 = 1
So 473840-72-1 is a valid CAS Registry Number.
