Check Digit Verification of cas no
The CAS Registry Mumber 128293-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,9 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128293-05:
(8*1)+(7*2)+(6*8)+(5*2)+(4*9)+(3*3)+(2*0)+(1*5)=130
130 % 10 = 0
So 128293-05-0 is a valid CAS Registry Number.
