344345-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 344345-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,4,3,4 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 344345-19:
(8*3)+(7*4)+(6*4)+(5*3)+(4*4)+(3*5)+(2*1)+(1*9)=133
133 % 10 = 3
So 344345-19-3 is a valid CAS Registry Number.
