Check Digit Verification of cas no
The CAS Registry Mumber 5057-93-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,5 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5057-93:
(6*5)+(5*0)+(4*5)+(3*7)+(2*9)+(1*3)=92
92 % 10 = 2
So 5057-93-2 is a valid CAS Registry Number.
