Check Digit Verification of cas no
The CAS Registry Mumber 61128-47-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,1,2 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 61128-47:
(7*6)+(6*1)+(5*1)+(4*2)+(3*8)+(2*4)+(1*7)=100
100 % 10 = 0
So 61128-47-0 is a valid CAS Registry Number.
