The CAS Registry Mumber 72057-19-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,5 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 72057-19:
(7*7)+(6*2)+(5*0)+(4*5)+(3*7)+(2*1)+(1*9)=113
113 % 10 = 3
So 72057-19-3 is a valid CAS Registry Number.
