5Check Digit Verification of cas no
The CAS Registry Mumber 5572-43-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,7 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 5572-43:
(6*5)+(5*5)+(4*7)+(3*2)+(2*4)+(1*3)=100
100 % 10 = 0
So 5572-43-0 is a valid CAS Registry Number.
