128278-11-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128278-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,7 and 8 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128278-11:
(8*1)+(7*2)+(6*8)+(5*2)+(4*7)+(3*8)+(2*1)+(1*1)=135
135 % 10 = 5
So 128278-11-5 is a valid CAS Registry Number.
