128544-08-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128544-08-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,5,4 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128544-08:
(8*1)+(7*2)+(6*8)+(5*5)+(4*4)+(3*4)+(2*0)+(1*8)=131
131 % 10 = 1
So 128544-08-1 is a valid CAS Registry Number.
