128726-28-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128726-28-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,7,2 and 6 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 128726-28:
(8*1)+(7*2)+(6*8)+(5*7)+(4*2)+(3*6)+(2*2)+(1*8)=143
143 % 10 = 3
So 128726-28-3 is a valid CAS Registry Number.
