Check Digit Verification of cas no
The CAS Registry Mumber 2429-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,2 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2429-72:
(6*2)+(5*4)+(4*2)+(3*9)+(2*7)+(1*2)=83
83 % 10 = 3
So 2429-72-3 is a valid CAS Registry Number.
