Check Digit Verification of cas no
The CAS Registry Mumber 24139-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,1,3 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24139-57:
(7*2)+(6*4)+(5*1)+(4*3)+(3*9)+(2*5)+(1*7)=99
99 % 10 = 9
So 24139-57-9 is a valid CAS Registry Number.
