Check Digit Verification of cas no
The CAS Registry Mumber 7143-01-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,4 and 3 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7143-01:
(6*7)+(5*1)+(4*4)+(3*3)+(2*0)+(1*1)=73
73 % 10 = 3
So 7143-01-3 is a valid CAS Registry Number.
