28278-55-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28278-55-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,7 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 28278-55:
(7*2)+(6*8)+(5*2)+(4*7)+(3*8)+(2*5)+(1*5)=139
139 % 10 = 9
So 28278-55-9 is a valid CAS Registry Number.
