128272-65-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128272-65-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,7 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128272-65:
(8*1)+(7*2)+(6*8)+(5*2)+(4*7)+(3*2)+(2*6)+(1*5)=131
131 % 10 = 1
So 128272-65-1 is a valid CAS Registry Number.
