5Check Digit Verification of cas no
The CAS Registry Mumber 6428-55-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,4,2 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.Calculate Digit Verification of CAS Registry Number 6428-55:
(6*6)+(5*4)+(4*2)+(3*8)+(2*5)+(1*5)=103
103 % 10 = 3
So 6428-55-3 is a valid CAS Registry Number.
