Check Digit Verification of cas no
The CAS Registry Mumber 343-59-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 343-59:
(5*3)+(4*4)+(3*3)+(2*5)+(1*9)=59
59 % 10 = 9
So 343-59-9 is a valid CAS Registry Number.
