28719-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 28719-48-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,7,1 and 9 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 28719-48:
(7*2)+(6*8)+(5*7)+(4*1)+(3*9)+(2*4)+(1*8)=144
144 % 10 = 4
So 28719-48-4 is a valid CAS Registry Number.
