Check Digit Verification of cas no
The CAS Registry Mumber 331-43-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,3 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 331-43:
(5*3)+(4*3)+(3*1)+(2*4)+(1*3)=41
41 % 10 = 1
So 331-43-1 is a valid CAS Registry Number.
