Check Digit Verification of cas no
The CAS Registry Mumber 3343-01-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3343-01:
(6*3)+(5*3)+(4*4)+(3*3)+(2*0)+(1*1)=59
59 % 10 = 9
So 3343-01-9 is a valid CAS Registry Number.
