2449-19-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 2449-19-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,4 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2449-19:
(6*2)+(5*4)+(4*4)+(3*9)+(2*1)+(1*9)=86
86 % 10 = 6
So 2449-19-6 is a valid CAS Registry Number.
