128555-47-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128555-47-5 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, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128555-47:
(8*1)+(7*2)+(6*8)+(5*5)+(4*5)+(3*5)+(2*4)+(1*7)=145
145 % 10 = 5
So 128555-47-5 is a valid CAS Registry Number.
