Check Digit Verification of cas no
The CAS Registry Mumber 128450-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,4,5 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128450-34:
(8*1)+(7*2)+(6*8)+(5*4)+(4*5)+(3*0)+(2*3)+(1*4)=120
120 % 10 = 0
So 128450-34-0 is a valid CAS Registry Number.
