128913-54-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128913-54-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,1 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 128913-54:
(8*1)+(7*2)+(6*8)+(5*9)+(4*1)+(3*3)+(2*5)+(1*4)=142
142 % 10 = 2
So 128913-54-2 is a valid CAS Registry Number.
