Check Digit Verification of cas no
The CAS Registry Mumber 5489-77-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,8 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5489-77:
(6*5)+(5*4)+(4*8)+(3*9)+(2*7)+(1*7)=130
130 % 10 = 0
So 5489-77-0 is a valid CAS Registry Number.
