The CAS Registry Mumber 1057516-18-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,5,1 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1057516-18:
(9*1)+(8*0)+(7*5)+(6*7)+(5*5)+(4*1)+(3*6)+(2*1)+(1*8)=143
143 % 10 = 3
So 1057516-18-3 is a valid CAS Registry Number.
