Check Digit Verification of cas no

The CAS Registry Mumber 473435-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,3,4,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 473435-89:
(8*4)+(7*7)+(6*3)+(5*4)+(4*3)+(3*5)+(2*8)+(1*9)=171
171 % 10 = 1
So 473435-89-1 is a valid CAS Registry Number.
