Check Digit Verification of cas no
The CAS Registry Mumber 5928-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,2 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 5928-72:
(6*5)+(5*9)+(4*2)+(3*8)+(2*7)+(1*2)=123
123 % 10 = 3
So 5928-72-3 is a valid CAS Registry Number.
