Check Digit Verification of cas no
The CAS Registry Mumber 457060-14-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,0,6 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 457060-14:
(8*4)+(7*5)+(6*7)+(5*0)+(4*6)+(3*0)+(2*1)+(1*4)=139
139 % 10 = 9
So 457060-14-9 is a valid CAS Registry Number.
