The CAS Registry Mumber 6057-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 6057-78: (6*6)+(5*0)+(4*5)+(3*7)+(2*7)+(1*8)=99 99 % 10 = 9 So 6057-78-9 is a valid CAS Registry Number.
