Check Digit Verification of cas no

The CAS Registry Mumber 201743-57-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,7,4 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 201743-57:
(8*2)+(7*0)+(6*1)+(5*7)+(4*4)+(3*3)+(2*5)+(1*7)=99
99 % 10 = 9
So 201743-57-9 is a valid CAS Registry Number.
