Check Digit Verification of cas no
The CAS Registry Mumber 5402-20-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,0 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5402-20:
(6*5)+(5*4)+(4*0)+(3*2)+(2*2)+(1*0)=60
60 % 10 = 0
So 5402-20-0 is a valid CAS Registry Number.
