2819-57-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2819-57-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,1 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2819-57:
(6*2)+(5*8)+(4*1)+(3*9)+(2*5)+(1*7)=100
100 % 10 = 0
So 2819-57-0 is a valid CAS Registry Number.
