344249-71-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344249-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,2,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 344249-71:
(8*3)+(7*4)+(6*4)+(5*2)+(4*4)+(3*9)+(2*7)+(1*1)=144
144 % 10 = 4
So 344249-71-4 is a valid CAS Registry Number.
