Check Digit Verification of cas no
The CAS Registry Mumber 7343-16-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 3 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 7343-16:
(6*7)+(5*3)+(4*4)+(3*3)+(2*1)+(1*6)=90
90 % 10 = 0
So 7343-16-0 is a valid CAS Registry Number.
