128555-51-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128555-51-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,5 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128555-51:
(8*1)+(7*2)+(6*8)+(5*5)+(4*5)+(3*5)+(2*5)+(1*1)=141
141 % 10 = 1
So 128555-51-1 is a valid CAS Registry Number.
